How to use some of the essential funcitons on your calculator. Please leave comments if you have any questions or you have questions about how to do other things on your calculator.
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!
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.
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 .
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.
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)
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.
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!
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?
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 🤞🏼
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.
You can't multiply polynomials or radicals with the TI30 XIIS. Most calculators won't do variable operations. Some calculators like the TI30 S or the TI83 will do radical operations if they are set to Mathprint mode. The TI 30 XIIS doesn't have a Mathprint mode (to the best of my knowledge). Sorry
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.
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: ru-vid.com/group/PLte95fLu7u9ukLz24TytI8v-gSrTn-vBs if that's what you're struggling with.
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?
