Using Your TI-84 Plus CE Part 3: Variables, Lists, Matrices

[KermMartian]

+Emily Vail Almost everything you need for most math classes is already built into the calculator, including all of the statistics and probability tools that "Using the TI-84 Plus CE" (see Table of Contents in the Manning link in the description) mentions in Chapter 9. Unfortunately, I haven't gotten around to making a video about that material yet.

How do I add an x value into a table that already has a list of x and y values?

[questionableuncle]

Is there a way to put in x as the number for x? So you could do things like (bx^2)/x=bx? Cause this would help with dividing out factors and simplifying

[yaboyconnor]

How do you store matrices? For example, I edited Matrix A so how do I save the changes I made??

[Brandonhulk]

How do i change the letters from lower to upper case?. My 2nd does lower case and my alpha does upper.

Be careful when you Enter the Mr. Ander....err....

[zacht-cv]

how do you get rid of the stored variable?

Great videos! need to learn this calculator in 2 days before an exam!

I have a problem with manipulating user-defined lists. Specifically, I cannot perform A = B+2 like I would L5 = L4 + 2. Can you please help me with this?

[ryryhc]

How do i clear the number assigned to the variable.

[israelojo]

Thank you! Quick question: I know how to perform L5 = L4 + 2 but if I create two new user-defined lists say A and B, I cannot perform A = B+2 (It does not work). Can you please help me with this?

I'm 19 years out of high school but am trying to pick up the TI-84 graphic calculator for programming purposes. It's highly portable and, with the right programming, can help me in the field with quick calculations.

I am not new to programming, even to TI-BASIC (though like I said, it's been a while). I'm trying to learn to store and use variables from my program. I have tried within my program using the STO arrow to assign values to variables, but it's not sticking. Do you have any suggestions?

My calculator is the TI-84 Plus CE with Python.

[vikasfotos]

How do I get rid of the variables without deleting all of the other data and setting that I have?

[carsonsears.]

On the calculator, it showsa button that says X, T, O, N. How do I choose O

[ravenjavier]

Could it solve a matrix that has a 8x8 dimension?

[jaystation]

how do you change X to either T, n or theta which is on the same button as X

[bharatchinchkhede]

Kindly tell me how fundamental constants are used in dinominators in any formula.

[javidbunyatov]

Can you please tell me why would I get an error entering a decimal into the matrix?

[bedamundo]

how can I install programs into the calculator such as the quadrati or distance? For some reason, I can't transfer the programs from a TI 84 plus calculator to my plus CE. I clicked receive first and then tried to transfer the programs, but it didn't work. it says error in Xmit or something. It would mean a lot if you could also create a video on how to do this..

Hi, this really helped. But I don’t know how to reset x back to what it was originally because I did what u do in the video... I saw another question of this but I didn’t understand your anwser. Any help is appreciated, thx.
