How to use a TI 30X IIS calculator

[@imkatiekateful]

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.

[@robhenderson1832]

Miigwetch! Thank you so much. As an old 50 something I need all the tricks I can find to pass this Math 040. This helps immensely.

[@DonnaTN]

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!

[@ladypinkbagsetc.9116]

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 .

[@mariellemusm.8039]

I have like 2 days with this one and I also need my math hiset equivalent ged for 4 days

[@TheOlavarria49]

And I thank you for that!!! I just got this calculator and didn't know how to use some of its functions, now I do. thanx!

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)

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!

[@kevinkennedy503]

What do you mean exactly? If you're talking about simplifying expressions with variables then answer is no, it can't.

[@bloodsweattaers9654]

OMG this was sooo helpful I just got this calculator today and I had no I tea how to use it, THANKS!

[@skippyelchulo69]

Thank you for this video. These buttons look confusing without understanding thier functions. :) thanks for the vid!

[@kevinkennedy503]

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.

[@anonymous_192]

when sven solves something felix doesnt felix: WHATTT sven has big brain

[@Yupperoni]

hello i wonder how to turn mixed numbers into decimals on this calculator

[@kevinkennedy503]

On your calculator you should see a function that says "f< >d". I think it comes up in the video.

[@wakemeup5709]

Really helped me a lot.

[@tango108]

How do you use it if it's natural l9g division ?

[@YozStudios]

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!

[@kevinkennedy503]

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.

[@jenniferjanmarie75]

Thanks this was so helpful

[@kellyhatz4977]

what about square roots? what keys do I use?

[@xanderfloats]

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?

[@kevinkennedy503]

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.

[@roxygirlx12]

Can you simplify radicals without using decimals??

[@jrcgjhughes]

What do you do when you have a negative for example 11 with a - 4 power x 11 with a -4 power ? thanks

[@kevinkennedy503]

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)

[@angelicaalvarado261]

This video is amazing.

[@RandyEndsley]

Thanks. Very helpful.

[@jlpetty85]

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".

[@kevinkennedy503]

+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.

[@abood.3m562]

love u from the future :)

[@gtigio5067]

Can you simplify radicals or simplify square roots on that calculator??

[@kevinkennedy503]

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.

[@lisareardon3029]

Can you do the hypotenuse on the TI30IIS? thank you

[@kevinkennedy503]

+Lisa Reardon You can use it to evaluate square roots but it doesn't have a hypotenuse function per se.

[@pablotafur539]

How do you multiply fractions? Such as (27 and 2/3) times 1/2

[@kevinkennedy503]

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.

[@deejay6869]

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.

[@DaisyRodriguez-oj6jl]

Very helpful thank you 😁

[@angelheun9355]

How do you graph on this calculator? Can you do graphs?

[@kevinkennedy503]

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: kzbin.info/aero/PLte95fLu7u9ukLz24TytI8v-gSrTn-vBs if that's what you're struggling with.

[@fermiLiquidDrinker]

Angel Morrell For a cheaper graphing calculator go with something like a Casio FX-9750 G II, it is inexpensive and is great for algebra and below.

[@jackstarkey2104]

[@ashes2ashton490]

What about variables a pnd coefficients?

[@kevinkennedy503]

+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.

thx that helped a lot

[@ATömmyDarr]

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

[@kevinkennedy503]

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.

[@ATömmyDarr]

Thanks for the info I also recently purchased a TI 30xs so much better than what I was using

[@keiraj3442]

How do you use the inverse button for sin, cos, tan

[@kevinkennedy503]

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.

Is there any way to do Equations with Fractions on the 30xIIs? Example x+11/14 = -11/14 x=?

[@kevinkennedy503]

No. Like I've said before: you can only really use this calculator to do calculations, it won't solve equations for you.

[@GaulonLance]

Ok thanks what calculator can? Or do you recommend one?

[@kevinkennedy503]

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.

[@ScarletxVelvet]

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?
