This was a great video. My 7th grader was advised to get this calculator for school. I know he is going to be overwhelmed by all of the buttons. Your video covered the types of calculations he will need it for. This is perfect.
GOD BLESS YOU!!! You make this SO clear and easy to understand! PLEASE DO MORE WITH THE TI30XIIS calculator! Nobody EVER explained all of that to me before! The last time I took a math class was 35 years ago! (And we DIDN'T have calculators THIS confusing... if any!) In my Statistics class (BER345) I think the teacher assumes we understand HOW to use EVERYTHING on this calculator (mentioned above!) PLEASE DO MORE VIDEOS on EVERY SINGLE type of function you can do on this calculator! Thank you SOOOOOOOOOOOOOOOOOOOOO much!!! GOD BLESS YOU!
Thank you for taking the time to make this tutorial video. You have been extremely helpful. Your presentation style and delivery was so easy to follow.
Wow Amazing! I have been trying to find out how to use this for 3 days... You did it in 6 minutes! BRAVO!!! I did not know what these were. I am studying to pass my Math GED and was lost... I missed it by 2 points because I did not know how to use the calculator. Thank you so much. My test is on the 5th of November. I have passed all of the rest .
To do e to the - 7 power find the e^x function (it's the secondary function for Ln) and then put in - 7 (make sure to use the ( - ) and not the subtraction button) OR find the e constant and then use the ^ function and then put -7 (again make sure to use the ( - ) and not the - subtraction button)
thank you. i've watched serial videos but i understood you. Please do more, i'm stating class in Aug and i have never used an scientific calculator so thank you again. Signed Frustrated
excelent tutorial!!! it really helped me to understand the basics of it! would you be kind to do a tutorial about how to do algebraic computations on this calculator? I know is not designed for that purpose but I know that you know a way to do it, so, please! I'll really appreciate it!
Sven: The calculator does not have a generic Log function. It has two fixed based log functions: Log, which is log base 10, and Ln, which is log base e. If you want to evaluate a log in a different base you need to use the change of basis formula: Log(base a) of b = Log(b)/Log(a) So in your example you would use Log(9)/Log(3) to get 2 I hope that helps.
I love how you explain the use of this calculator what if I am doing something like this 2square root -25x^12y^23 on this calcutor And i want to store X and y into the TI30
In other calculators there is a x to the power of y button (it looks like a x with a little y by the top right corner). What is it on the Texas Unstrument TI-30X IIS?
Type in: 11^-4 x 11^-4. You will end up with a decimal. You should be able to use the 2nd, fd function to convert it to a fraction (although in this case it may be too large to convert). Alternately: without the calculator your answer would be 11^-8 or 1/(11^8)
No. You cannot graph with this calculator. For that you would need a graphing calculator like a TI 83 (which will run you at least $80). I do have some videos about graphing lines: ua-cam.com/play/PLte95fLu7u9ukLz24TytI8v-gSrTn-vBs.html if that's what you're struggling with.
What about radicals? For example square root of 80 always gives me a decimal. Is there a way on this calculator to get that radicand in simplest form, while still being a radical?
Alexander Galdamez This calculator cannot simplify radicals in radical form. The TI 30XS can. This one cannot. I plan on putting out another video soon on how to simplify radicals.
Kevin, do you know to get the calculator to display, e.g., cos^(-1)[0] as "pi/2" instead of "1.5707"? I've already put it in radian mode using the [DRG] button. Thanks for the video and any help!
There really isn't a way to do that on this calculator. The TI 30 XS has a "math print" mode and can do that I think. What you can do is after you get your answer, divide by pi and then change it from decimal to fraction. That's the best I've got. I hope that helps.
what button is the carrot button on a TI-30xa i eventually found fraction to decimal plan on making similar videos myself when i get well informed enuff
On the TI-30XA there is a x^y button. That particular calculator can be more difficult to use, primarily because it does not display a visual confirmation of the calculation you are carrying out. When you use that function you will type in the base first the hit the x^y button. The screen may clear and then you will type the exponent. Then you will hit enter. I hope that helps.
Above the trig functions on your calculator you'll see Sin^-1, Cos^-1, and Tan^-1 which are the trig inverses (and not the reciprocals). You use them pretty much the same ways as the regular trig functions.
@@Tyronne-o7y on the TI30XIIS there is a A b/c button. That's your fraction button. There is also a secondary button fd which converts from fraction to decimal.
I need to figure out how to put negative numbers under a radical sign. I have tried using the (-) negative button next to the 0, but it comes up as "domain error".
+Jenna Petty Whenever you take the square root of a negative number, you get a complex number as a result. The TI 30X IIS cannot do calculations with complex numbers. You're getting that "domain error" because you are typing the calculation correctly but, since the answer is a complex number, your calculator cannot give you a result. If you're attempting to find a square root of a negative number, remove the negative sign and bring it out of the radical as "i". Then find the square root of the positive number remaining. If you're doing this as part of using the quadratic formula then that means your equation has no real roots.
Thanks for this video. I downloaded the Instructioj Manual (.pdf) for this calculator, but all I got was a teacher's instruction guide. It might as well have been reading a Jurisprudence legal document, for as much sense as it made to me. Just curious: Do you have that manual to look over? And is it just me, and it's ridiculous in its ex;planations? Or does it make perfect sense to you? I'm new to scientific calculators, so it may just be my inexperience. Have you, or could you, done/do a review of the different calculator buttons? Just a quick explanation of what the different buttons are designed to do. Else I fear I'll have to traipse into the teacher's guide some more. Ugh.
Thanks so much for this! SO helpful! I do a question, though. I am doing college chemistry right now and need to find the rate constant using a calculator. On most calculators people use a STAT button... does mine have that ability? I see a STATVAR button... I would so appreciate any help.
This is covered in the video. You use the fraction button (the a b/c button). Type in in this example, 27 a b/c 2 a b/c 3 * 1 a b/c 2. You're going to get a mixed number when you do this. If you need to convert it to an improper fraction that's covered in the video as well.
+Kylie Ortiz You can't evaluate expressions with variables on this calculator. Most calculators don't have the ability to simplify algebraic expressions. You're going to have to learn how to do that by hand. Sorry.
Lance Gaulon Honestly (and I know you don't want to hear this): The time, effort and money you'd spend learning how to do it on a calculator would be better used learning how to do it by hand and most of the time the answer you get will not be pretty. In the example you gave: you would subtract 11/14 from both sides. This would make your equation x = -11/14 - 11/14. You CAN use the calculator to evaluate -11/14 - 11/14 (you get an answer of -11/7) If you really must use a calculator to do this you'll need a TI 83 calculator but the process is really not straight forward.| I will try to address solving equations with fractions in the next video I make.
+Kaitlyn Murtagh Using generic powers is covered in the video. Skip ahead to about 4:37 for that section. As far as square roots are concerned: If all you want is a decimal approximation then all you need to do is use the square root function (which is the 2nd function for the x squared button).

Hi, thank you so much for the video, it was VERY helpful! Can you do exponential equations on this calculator? The problem I can't figure out is log 15 over log 13, I'm suppose to round it 3 decimal places on the calculator, I don't have a clue of how to do it. I know the answer is ~2.465, can you help me please?
Lisa E if you type in Log(15)/Log(13) you get 1.056, which is not the answer you're looking for. I feel like I'm missing something. Would it be possible to get a picture of the question you're working on?
Clarify: do you want to switch your calculator from degree mode to radians mode or do you want to convert degree measurements into radian measurements?
You can't. Scientific calculators can't simplify algebraic expressions. Most graphing calculators can't either. In this case you are multiplying the two exponents together which gives you x^2.
You don't. You're not solving it you're simplifying it. Each of your exponents get reduced by 2 and the 5 is left over x^2 because it doesn't have any factors of x to cancel. You should end up with 3x^5 +4x^4 + 5/x^2
Ok I don’t know what I did but every time I press the enter button it adds a 7 to me answer So like I’ll put 7*7 enter and it adds a 7 and the answer is 539 your help is much appreciated 🤞🏼
When I calculate 6.9 x 10^-8 and divide it by 4, I get 0.000000017. However, I should be getting 0.00000001725 like in other calculators. How can I view more numbers?

thank you now it makes me easier to do my homework about fractions
You are a genius. How huge was this!!!
Where can i find the abc button on my Ti-34II ?
Can you simplify radicals or simplify square roots on that calculator??
No, the TI30XIIS won't simplify radicals for you. I really need to get around to making a video on how to do that by hand for people.
What do you do when you have a negative for example 11 with a - 4 power x 11 with a -4 power ? thanks
Type in: 11^-4 x 11^-4. You will end up with a decimal. You should be able to use the 2nd, fd function to convert it to a fraction (although in this case it may be too large to convert).
Alternately: without the calculator your answer would be 11^-8 or 1/(11^8)
