Gauss's head would explode if he watched this video.
My own calculator will be delivered to me on September 12, 2018. Interestingly, back in September 1983 when I was at technical college I used a Sharp 1401 Pocket Computer which was programed in BASIC language. It would interesting to see how the TI Nspire CX CAS handles transistor circuit equations based on the Shockley diode equation. The year 1983 seems like the Stoneage now.
I'm way too uninformed to know what you mean by those equations, but that TI calculator truly is great. I wonder if it also worked for you as good as it has for me.
The TI-nspire CX CAS is a great calculator. But if TI wants you to spend so much money on one, don't you think they ought to know what CX stands for in the first place, especially if they care so much? Nobody in Dallas could tell me. Do you or any of your viewers know?
Thanks for the tips!
This is great. Something I may return to. Thanks. One thing that would help but may be quite a bit of work would be to create a table of contents. Like
Adv Calculator functions: 15:00
Alright, done!
Very very nice. I love it when someone covers a lot of ground succinctly and concisely with practical "tips" en passant.
Seriously - thanks. Just got my calc and trying to resolve it with my old HP 48gx which is a bit long in tooth.
Would love to see you expand on this video - like drawing tangents to curves, unit conversion, installing libraries and apps.
Ti is way too skimpy on the info for this thing.
The tip at 12:20 can be done even easier. Just hold the delete button for 2 seconds
How is it that you're getting fractions as answers and I'm getting decimals? How do I switch this??
thank you so much, you're a legend :)
Thanks
Thanks for taking the time to do this! Super helpful👌
Hello. I have a TI spire CX II-T CAS. How can I design a vector in 3D? For example [3; 2; 6]. In 2D is ok but in 3D?
Thank you for very informative video 😊
How would I access the

I really need your help on this would you know how to access this or is it no longer on the cx cas
March of 2018, latest updates, at 1:34 mins, you got 9/2000 from 4, 5, EE, - , 4, Enter... that no longer happens. It goes straight to 0.0045. You no longer get the fraction, 9/2000. I don't know if I like that. In fact, you then have to enter the number, go to Menu, Number, Approximate to Fraction. Bummer!
In Document Settings, do you have your Calculation Mode set to Exact?
Calculation mode is set to Auto and thanks by the way. Oh, I'm on v4.5.0.1180. This is a great video. I've been through it twice and even wrote myself a text file on my PC for reference. I also noticed when you took the integral of the parabola around 12 mins that there's a box for " lower boundary" and "upper boundary", so I typed in a value and Enter for both, but forgot the negative sign on one entry. I figured out how to delete / remove that grayed out area. I got on the x axis points and pressed ctrl del for anyone interested.
aaaah, i was wondering what i was doing wrong
Very informative video, thank you.
Great video. It helped me get started. Thank you for sharing.
I'm very familiar with TI 89 Titanium and is very happy with its electrical Apps functions, that is not in TI-nspire CAS; very bad.
But I am going to buy one of the those new TI CX, that has all the good old and new functions, that cover high level Maths, DSP, Electical problem, Random and stochastic process. Which one of those would you recommend to me?
Super helpful!Thank you!
I recently purchased this calculator for my nephew to take the SAT test. Do you also provide personal tutor instruction or can you provide the contact information for a good tutor for this calculator? Thank you so much in advance.
Really really helpful! Thank you :-)
Thanks this was really helpful
Thank you for this very informative video!
How can i change the value of a variable?
You can just assign it again with the sto→ key.
Thanks you for making this
Thank you for your video, it was very helpful. Can you please tell me how to delete variables that I created?
Sure, it's just "DelVar x", where x is the name of the variable.
how do you reset the calculator? is there a way to delete everything existing and reset the thing like in the ti84?
NowItsKevin there is a very small button on the back of the calculator, which u can press to delete everything. but u probably have to use a toothpick or something small to be able to press it
Drop it in a Bucked of water for 7 minutes and all is gone !!!
not loud enough and too glib in the delivery ; this is new

Hey MM, so I'm following a host on youtube and he wants the included angle of a triangle using the Cosine Rule and I get cos(c)=67/80 or 0.8375. My cx cas is set to Radians. Is there any easier way to convert that to 33.1 degrees than by going through this mess... change radians to degrees (you have to set to default), enter cos^-1(0.8375) ctrl enter? Thanks
You can always just get the answer in radians, then multiply by 180/𝜋
Thank you. I'm in radians and I get cos(c)=0.8375 How do I do that? How do I get the answer in radians to then multiply by 180/pi? Originally, it was cos(c)=(8^2+20^2-14^2)/2*8*20 Now the guy that was teaching wanted the answer in degrees, so he told his kids to just use "Shift", but they were using a TI 84 or something.
Just input cos^-1(0.8375) * 180/𝜋
Around 20 mins, you converted 7_m + 8_cm and got 7.08 _m, but if you enter 1_yd+1_in, you get 0.9398m instead of 37 inches - weird! Why would you get metric to metric in the one instance, but not standard to standard in the other? Reminds me of the time back in the 1970s when calculators first came out and my Dad paid $400 for that RPN Hewlet Packard *(^@*&&? piece of crap and he showed it to me and I promptly entered find the cube root of 8 and it came out 1.994779308309871874 or whatever :) He just about jumped out of his skin after paying $400 for that and he said, why on earth was that the first thing you tried? I said, it just seemed like the logical thing to do.
