One can obtain a black/red variant by purchasing the European version CX II T CAS, which is identical except for the top accessory port (not the bottom one), which is only necessary if your instructor requires you to connect a wireless dongle to your calculator.
Fun fact: I popped the summation problem into a calculator app on my phone (running a Snapdragon 865+), and it took 9-10 seconds each time to calculate. I tested the same problem on another phone with a midrange MediaTek chip (Dimensity 720) and the same app, and it took about 15 seconds to calculate each time. I know it's kind of an apples-to-oranges comparison, but I thought it was a little interesting 😁
I just did this test on my hp prime g2 and it took only about 0.3 - 0.5 seconds. So it is not only power but optimisation as well. Which is interesting as well.
It depend on what app you are using and btw the answer for the summation problem on the video is straight up wrong, the real answer is less than 1 and idk how this calculator got 30011
It's great to know the CX II is faster (and therefore better) than the CX , but what does CX stand for in the first place? I called TI to ask them the same question, but the girl who answered the phone didn't know TI made an nspire calculator and even asked me to send a picture! It's wonderful to know I should buy one of these, but wouldn't it also be smart to know what I'm buying? If any of your viewers know, please reply.
CX probably means Color and then X to sound more appealing. Names mean a lot. TI nSpire CX II CAS sounds way more high tech, faster, appealing, etc. than the HP Prime, but the HP Prime funnily enough, has the better hardware. About the same in capability though, one is just faster and easier to use.
The version II has python, but TI BASIC isn't that hard to learn, programming concepts are relatively the same between languages and my guess is that they are both pulling from the same library.
@@kodiererg i’m only just starting python now, but i can already tell there are big differences. ti-basic is a very, well, basic language. admittedly, without the ability to connect to the internet, python’s lure is diminished, but it remains infinitely more powerful than basic.

My old HP Prime (first generation) calculates the Sum formula in about 2 seconds and the new one is more than 2 times as fast. 6.4 seconds is really slow. It completely replaced my TI nSpire CAS.
If you do require the time and efficiency and not mind the bugs in some programs or the running procedure, choose HP Prime [or just run in the desktop]. I do not know the pros and the cons between TI-CXII CAS and the the HP Prime (v2) in some aspects or in the fields, maybe some people experienced and skillfully to use them well, by long time trying and explore with many fail cases, to overcome the input difficulties. My previous head director can use his advanced sci-calculator well with the input program many years ago. I should have the same status to like him!

I have a CX CAS first version. when I attempt the summation in your example, x=1 to 30000, 1/e^x I receive "Resource exhaustion Cannot complete calculation". Yours worked! Anyone have a solution?

I’d say it wouldn’t be worth it to get a new calculator for the SAT if you already have the ti-84. As long as you have solid algebra skills you should be fine.
Depends on your personality, for SAT no calculator section, a CAS calculator can save a lot of time, however it does take some time to become very fast with all the functionality. For the calculator section it can save some time, but most of the questions in the calculator section can be done without calculator, and the CAS functionality isn’t as much of a help.
Perhaps the latest one is strong more but we have to explore its advanced functions and know more practical examples in the work fields would be better! EVEN you just got a low-class sci-calculator!
This is a very bad Texas Instruments policy. They sold a fairly expensive calculator (CX CAS) a few years ago with limited possibilities to use it other than for education, then they sold an expensive Rover to it, and now they cut off the owners from the possibility of using a new programming language, Python. It's a shame, dear TI.
I bought Cx ii from Amazon. Now there is an issue with it. So it was dead and was off for while so I decided to charge it but after sometime when I tried to turn it on its menu screen appeared which was blur and then it got switched off.

It may be a good upgrade, you can do much more with either one of these than you can with the TI-83. Both are allowed on the SAT but maybe check with your math teacher about using it for your math class (my guess is it they would be fine with it). Having a Computer Algebra System calculator on the SAT may give you a slight advantage but it won't be life changing. What is very important for the SAT though, is that you are familiar with whatever calculator you are using. So it wouldn't be a good idea to get a new calculator a week before your exam for example, because you won't know where all the functions and things are as well as you would on a calculator that you'd been using for a while.

The two top of the line calculators on the market are the TI Nspire CX CAS II and the HP Prime. The primary difference between the two is the CX is focused on education. It has been invaluable for me in the classroom, especially when combined with the extremely pricey "Made Easy" apps (google "Nspire Made Easy"). These apps wont help much on tests, but they will help understand more simple problems where you might not be clear on what to do. The Prime is the "real world" calculator. It is faster, and the touchscreen makes it so much easier to use for things like exploring a graph and visualizing your derivatives and so forth, BUT, it is not intuitive in the way you input commands. Compound that with the fact that the battery will drain in 2 days, whether you are using it or not, and it makes it pretty obnoxious for school where you may not have access to a wall outlet to charge it if you need to use it in a pinch. Basically, this is the major problem with the Prime is that when you need it, the battery will likely be dead. The Nspire uses templates. You tell it to make a function, there is a box that indicates where the numbers are going to go. It basically makes the text look like you would see it in a textbook, virtually eliminating placing numbers in the wrong place. The Prime is more command line like, you input the command and enter numbers in the command and hopefully you have put the numbers in the right place. Luckily, the Prime has builtin documentation that is very good (one area the Nspire lacks) to help both to find the correct command and to use the command correctly. One last thing, and this may seem like a small thing, but the Nspire has a full keyboard, where the Prime does not. This makes inputting commands on the Nspire significantly easier. They each have their place. The Prime is better in the real world, aside from the bizarre math bugs you will find should you use some weird function with just the right numbers (HP's quality control is a bit strange), but it is highly unlikely that you will ever run into this issue, and if you keep the firmware up to date, most of these issues have been since resolved. The Nspire on the other hand is great for classroom settings where you have controlled math problems that fit a specific format seen in text books. I have both, I use both depending on my needs. When I need to visualize a graph, the Prime is great, when I need to calculate a math problem, the Nspire is my goto. I would personally recommend getting both because they are really two different calculators with different design decisions behind them. Also, reverse polish notation is overrated, especially on the prime. For whatever reason, the calculator runs in two modes (CAS and NonCAS) and the mode you most likely will use all of the time (CAS mode) does not even support reverse polish notation. CAS mode is what lets you solve for variables like X, Y, or Z. Without it, you cant solve for variables in the traditional sense.
I tried the sum(1/e^(x),x,1,30000) on my t(rusty) old TI-89 Titanium - just for laughs - it took more than 8 minutes and yielded (e^(30000) - 1)(e^(-30000)) / e - 1. Wow!!
Hi! I have 2 libraries for Laplace transforms, they are called specfunc and cmplxanlys, the first one you can find it in TIuniverse the second one in ticalc.org, google the name of the library and the website, you should be able to find them in zip file, you download the library unzip it and then with TI Student software on your PC you transfer the .tns file to the MyLib folder on your Nspire, after that go to your calculator on scratchpad press doc and then Refresh Libraries, now by pressing the Catalog Key and going to the 6th tab you should see a folder with either name of the library, enter on either and the available functions will show up, in order to know how to input the information for each function you will want to open the .tns file on the Nspire or the PC software in order to read the instructions that the author has provided for using the library he developed. I would recommend you to try many libraries since some of them might be easier for some things and other might give more functions than others, in this example specfunc is capable of doing Laplace transforms with Dirac Delta and Heaviside form, which might be useful for you weather cmplxanlys has other functions that might be useful for you as well, let me know if you need more help!
On the TI-nspire you can press [menu] [4] [4] to bring up the limit template. Then to enter infinity as your approach, press the [pi] key (left of the letter keys) and then scroll to the right to select the infinity symbol.
@@mal0gen Example:solve(x^2=4,x) returns x=-2 or x=2 on a CAS calculator such as a TI-Nspire CX II-T CAS or TI-89 but solve(x^2=4,x) on a non-CAS calculator such as a TI-Nspire CX or TI-84 Plus returns an error.
A big difference is the computer software. Only by buying versin 2 you get the CAS student software. Otherwise you only have the one without CAS, which is not that useful, and you need to buy it separately.
TI makes inferior calculators. The only real reason they’re still used in schools is because it would take too long to switch, and because people in America think they’re better. A Casio FX9750GII actually graphs faster than a TI-84 Plus, at half the price. But we still just use TI.
The Prime does the sum with 12 signifact digits, the Nspire an ti 89 with 14. The Prime is a calculator very fast but has low precision for a device so fast.
@@ChadBeetle Yeah but I don't want them continuing to add STEM based features because only a handful of classrooms would have this network of calculators
I wonder why TI is using cheaper and slover processors than other brands like Casio or HP? Also some of TI's functions are programmed rather strange (and slow) ... :(
My Hp prime g2 blows those times out of the water. the prime g2 does those calculations nearly instantly. But they do better than my ti-89 titanium it takes approximately 550 seconds to calculate that sum, lol.
they should at least sell you a separate keyboard for people that just want to use it outside of exams, would be a lot more useful to make files with a QWERTY keyboard.
My school forced us to buy this crap (v1) because its "save" for exams. But because they never forced us to update the OS everybody can use ndless & nloader and a little bit of coding scill to exploit their calcs for exams.....

HP Prime
The two top of the line calculators on the market are the TI Nspire CX CAS II and the HP Prime. The primary difference between the two is the CX is focused on education. It has been invaluable for me in the classroom, especially when combined with the extremely pricey "Made Easy" apps (google "Nspire Made Easy"). These apps wont help much on tests, but they will help understand more simple problems where you might not be clear on what to do.
The Prime is the "real world" calculator. It is faster, and the touchscreen makes it so much easier to use for things like exploring a graph and visualizing your derivatives and so forth, BUT, it is not intuitive in the way you input commands. Compound that with the fact that the battery will drain in 2 days, whether you are using it or not, and it makes it pretty obnoxious for school where you may not have access to a wall outlet to charge it if you need to use it in a pinch. Basically, this is the major problem with the Prime is that when you need it, the battery will likely be dead.
The Nspire uses templates. You tell it to make a function, there is a box that indicates where the numbers are going to go. It basically makes the text look like you would see it in a textbook, virtually eliminating placing numbers in the wrong place. The Prime is more command line like, you input the command and enter numbers in the command and hopefully you have put the numbers in the right place. Luckily, the Prime has builtin documentation that is very good (one area the Nspire lacks) to help both to find the correct command and to use the command correctly.
One last thing, and this may seem like a small thing, but the Nspire has a full keyboard, where the Prime does not. This makes inputting commands on the Nspire significantly easier.
They each have their place. The Prime is better in the real world, aside from the bizarre math bugs you will find should you use some weird function with just the right numbers (HP's quality control is a bit strange), but it is highly unlikely that you will ever run into this issue, and if you keep the firmware up to date, most of these issues have been since resolved. The Nspire on the other hand is great for classroom settings where you have controlled math problems that fit a specific format seen in text books. I have both, I use both depending on my needs. When I need to visualize a graph, the Prime is great, when I need to calculate a math problem, the Nspire is my goto. I would personally recommend getting both because they are really two different calculators with different design decisions behind them.
Also, reverse polish notation is overrated, especially on the prime. For whatever reason, the calculator runs in two modes (CAS and NonCAS) and the mode you most likely will use all of the time (CAS mode) does not even support reverse polish notation. CAS mode is what lets you solve for variables like X, Y, or Z. Without it, you cant solve for variables in the traditional sense.
@@joshuagardner894 thanks mate, I'll get nspire for now
I have the CX II and when I tried the summation equation it gave me a "resource exhaustion" error 💀
found a solution btw: ctrl + enter or turn CAS off
As duas executa Python?
Can the python in CX II invoke a call to Nspire's function, such as isPrime()?
u shud be able to run it in the py shell I'm not sure abt the calc section tho
@@rohi_21 Is there a python shell on the calculator? If so, cool! How many libraries does it support?
I tried the sum(1/e^(x),x,1,30000) on my t(rusty) old TI-89 Titanium - just for laughs - it took more than 8 minutes and yielded (e^(30000) - 1)(e^(-30000)) / e - 1. Wow!!
Not to brag, but my Ti-84 Plus only took 22 seconds to throw an error message.
my ti84 plus ce took 4 seconds, heh.
and my casio fx-570sp x ii classwiz took a second...
My TI-84 Plus gives misleading an 'ERROR:Overflow' error after 5 seconds with sum(seq(1/e(X),x,1,30000,1))
The TI-30X Pro MP also after 10 seconds
the big difference is you can use commands for draw from programs and the other is python
Sirven los mismos .tns de la cx 1 en la cx 2?
if I want to install laplace file in this .
how can I do.
who can teach me👋
Hi! I have 2 libraries for Laplace transforms, they are called specfunc and cmplxanlys, the first one you can find it in TIuniverse the second one in ticalc.org, google the name of the library and the website, you should be able to find them in zip file, you download the library unzip it and then with TI Student software on your PC you transfer the .tns file to the MyLib folder on your Nspire, after that go to your calculator on scratchpad press doc and then Refresh Libraries, now by pressing the Catalog Key and going to the 6th tab you should see a folder with either name of the library, enter on either and the available functions will show up, in order to know how to input the information for each function you will want to open the .tns file on the Nspire or the PC software in order to read the instructions that the author has provided for using the library he developed. I would recommend you to try many libraries since some of them might be easier for some things and other might give more functions than others, in this example specfunc is capable of doing Laplace transforms with Dirac Delta and Heaviside form, which might be useful for you weather cmplxanlys has other functions that might be useful for you as well, let me know if you need more help!
Good review. You have done some good videos !
The first thing I noticed is that the new version burns through a battery charge in about half the time of the first version
That's likely because its CPU is twice as fast.
3:43 I'm doing the secretion on my titanium and it's been 5 minutes and it's still going 😐
Edit: it took around 7 minutes to finish the calculation
I really want to get the CXII CAS and CC CAS as well, which one should I get?
I have the cx cas and it’s really good
How do you apply infinity limits on a calculator
On the TI-nspire you can press [menu] [4] [4] to bring up the limit template. Then to enter infinity as your approach, press the [pi] key (left of the letter keys) and then scroll to the right to select the infinity symbol.
I want to see the finance app
Would you pay 30 bucks for the nspirecx or splurge for the new one?
clarify ti nspire cx without cas
What USB type connection is CAS II using?
Both versions use mini USB.
@@MathClassCalculator Thanks!
On the NEW one, do you have Python AND BASIC or, just Python?
Do an HP Prime one vs Casio fx cg-500
I have one of these for math and I was surprised it has a cursor
3:30 I finished to watch your video and write this comment, my FX-991EX still computing the sum.
my ti 36x pro takes maybe one hour for that summation idk it took so long i did something else
*flashback about plainrock124 smashes ti-nspire cx cas*
Very useful thanks you. I'm buying a used version 1.
Charging port
ngl I prefer the old style of interface, the new just one seems oversimplified to me
right
Ended up here while I was searching for a powerful calculator so I could comment on an Abacus video.
What is CAS?
special because you can solve more types of equations that you cant do on non cas calculator
@@mal0gen You also cannot do it on a TI-Nspire CX II-T CAS with CAS Mode=OFF or CAS Mode=Exact Arithmetic.
@@leonielobster7653 Uh, yeah, i know that. Still... it's not the same, theoretically, and unless you're on an exam, why the heck turn off CAS?
@@mal0gen Example:solve(x^2=4,x) returns x=-2 or x=2 on a CAS calculator such as a TI-Nspire CX II-T CAS or TI-89 but solve(x^2=4,x) on a non-CAS calculator such as a TI-Nspire CX or TI-84 Plus returns an error.
in 8th grade, starting a1 now :D
Just bought the version 1 becus it's 35 bucks instead of 60-70 second hand
A big difference is the computer software. Only by buying versin 2 you get the CAS student software. Otherwise you only have the one without CAS, which is not that useful, and you need to buy it separately.
That may have been the case 2yrs ago. Just received my gen1 and it came with a licensed key for student software.
You didn't mention python
Python was not available for the nspire at the time this video was made.
@1:52
*Le sigh*. I felt that man
I tried the benchmark at 3:30 on a HP Prime: under 1 seconds.
TI makes inferior calculators. The only real reason they’re still used in schools is because it would take too long to switch, and because people in America think they’re better. A Casio FX9750GII actually graphs faster than a TI-84 Plus, at half the price. But we still just use TI.
@@chuuisinsane But HP is an american company, soooo wtf?
it took ~1sec on my HP prime that is the first 2013 version
The Prime does the sum with 12 signifact digits, the Nspire an ti 89 with 14. The Prime is a calculator very fast but has low precision for a device so fast.
The worst window they got is on the TI-84. That thing is THICC!
I think another big difference is CXII support python
The Ti-Nspire series is way too focused on STEM-like projects, so I'm keeping my old CX CAS
...the cx cas is an nspire.
@@ChadBeetle Yeah but I don't want them continuing to add STEM based features because only a handful of classrooms would have this network of calculators
I wonder why TI is using cheaper and slover processors than other brands like Casio or HP? Also some of TI's functions are programmed rather strange (and slow) ... :(
My Hp prime g2 blows those times out of the water. the prime g2 does those calculations nearly instantly.
But they do better than my ti-89 titanium it takes approximately 550 seconds to calculate that sum, lol.
The Prime does the sum with 12 significant digits, the Nspire and the ti titanium with 14.
@@manueljoseblancamolinos8582 must be why it's so slow. LoL.
they should add qwerty keyboard
it would be banned in the exams
they should at least sell you a separate keyboard for people that just want to use it outside of exams, would be a lot more useful to make files with a QWERTY keyboard.
Ya it would be banned on exams
@@alexisbuwembo6052 why would a querty keyboard be banned and not an abcde keyboard like on this calculator? it would just make life easier
@@spicyy812 the sat exams do not allowed
Yo simplemente me compré las dos porsiacaso y no arrepentirme ... 🤣🤣🤣
The only thing I don't like about my nspire is that the keyboard isn't qwerty lol
EVERYONE GET THE FIRST ONE IF YOU WANT TO RUN GAMES. IT IS LESS POWERFUL, BUT THE SECOND ONE IS NOT OPEN TO GAMES LIKE DOOM
No, a jailbreak is coming in mid September for the second model for it to run games
anything above 80 bucks must have touch screen!
ill stick to the HP prime G2 then.
I still find it funny how these things get absolutely thrashed by a similarly priced phone at their own job.
Indeed.
My school forced us to buy this crap (v1) because its "save" for exams. But because they never forced us to update the OS everybody can use ndless & nloader and a little bit of coding scill to exploit their calcs for exams.....
