Hi, I have had a TI-84 Plus CE for a few years, and it has worked with no issues. However, today I was trying to compute a definite integral from 0-60 degrees for sin(x)dx and it was giving me 28.64788976 instead of 0.5. I made sure that “Degrees” is chosen in Mode. Does anyone have any suggestions as to why this isn’t working?

Is there a online website where I can create programs and download them to my TI-84 Plus CE-T?

I find it hard and impractical to write programs in my calculator. Is there a way to write programs to then download them to my calculator?

I have an exam comming up and the teacher let us do this since the goal is to understand the material and skip the intermidiate steps

I've been looking for some but the only one I could find wouldn't work.

I’ve been using the TI36X Pro and prefer it way more over the ti84 but only the ti84 is allowed on my calculus final. My prof doesn’t like decimals so we need answers in fractions, but ti84 solves in decimals. How can I change it (I already tried math->frac

What is an appropriate amount of storage to have left on my calculator? Some of the programs I am using take up a few hundred KB of space and I'm wondering how low I should go without many issues.

My TI84 randomly reset a couple of days ago and I wanted to reupload the programs i had on it, and this morning when I plugged in my calculator i got a prompt for an update, and thinking nothing of it i went ahead and got it, only to discover that my programs are no longer working. Checked online and apparently I f'ed up big time, it basically says everywhere not to update the software. The downgrader I found apparently doesnt work for 5.5> Any help?

Just wondering, as I bought a system with every model of trackpad, including the TI-84 Plus one. Does anyone know, can anyone test that?

Having an issue with my TI-84 Plus CE, given a code 43 in windows device manager whenever I connect the system in. Any ideas? Any questions will be answered.

Could there be a way where i can make a custom sprite with animations move around with just ti basic on the 84 ce plus?

Hi guys, I’m french exchange student in the US and took CPAA for math, and I said fuck no I’m not going through 20 synthetic division every day so asked my teacher if I could make a program for it. As a previous computer science worker the nice teacher gave me the go ahead.

And I’ve done it, but not being an utter moron/not hating myself too much I decided to do it in Python on my PC.

I tried to export the program with TI-Connect CE but it only export it in Ti-Basics (wtf is this) and as a result doesn’t work as it’s a python program.

Could someone help me exporting it to the Python App. (If I need to jailbreak it I don’t care, I just want it done).

The exact model is a Ti-83 Premium CE Python edition.

If you want the program I’ll be happy to share.

I downloaded pineapple cas and the latest library i put both downloads in archive but when I go to the program and hit enter the second time on pineapple cas i get an error message any help?

I just bought a TI 84 Plus CE python. Tried to jailbreak it, downloaded CalibrJr and Artifice, but it keeps saying no ASM programs found. It's OS 5.8.0.0022

I’ve been searching on if it is possible to write subs on the TI-84 Plus CE for my pre calc class. Any help would be appreciated. I’ve only figured out how to write y subs but I need to write 3sub25.

https://www.youtube.com/watch?v=F9FjmrHCIjE. I'm following this tutorial on how to mirror my computer screen to my ti-84 plus ce. Around the 2:01 mark where it tells me to run the application i installed, it doesn.t work, all i get is an error. Any advice?

I’m trying to retrofit a Nokia battery in the ti 84 plus ce but I need to know the resistance between the negative and middle pin of the battery which I don’t have . Can please someone do me a favor and measure it ?

I want to start by saying I’m not good at math. The last time I attempted intro to stats, I almost flunked because our midterm and final were heavily weighted and I panicked.

I have a TI-84 plus CE graphing calculator and I know how to download programs for it, etc… I just do not know how to use them effectively and I don’t know the best way to go about learning other than combing through YouTube videos which makes me too antsy.

I fairly certain that the path to an A grade in this class is hiding in this damn calculator. The problem is that instructors don’t always teach in ways that indicate what you’re learning can be done in two minutes on your calculator, and I’m fully remote, so I can’t just pick it up from classmates.

Anybody have any ideas how I use this next month to effectively learn my calculator?

I have a ti-84 plus, and I transferred flappy bird on there. When I checked, it wasn't on there but the files were there on the connect app. How does one fix this?

When I'm initializing lists I do, for example, :If not dim(LS:Then:1->dim(LS:End but sometimes it doesn't work so I do SetUpEditor LS before, and it works, but then with the simple press of the stat button, the player/user can edit all properties of the list, and I don't want that. What should I do? Or what do I need to know?

So like I got KnightOS 0.6.7-29-gccbbb16 installed on boot code version 1.02. It's a great OS but like, now I can't flash any other OSes to the calculator neither can I get it to detect on the connector software. Any help? I heard there's boot code combos that might help if anyone knows them.

Is there a good web site for hacking TI-84 Plus CE Color ?

Is there a good web site for information about the internals of the TI-84 Plus CE Color ?

I was using my calculator to 84 plus silver edition when I pressed the screen accidentally a weird ink spot appeared on it Can I Fix it or I'm cooked?

so, Im having this one issue with calc2keyce where I have the program and exe and I run It and It doesn't do anything, instead the calculator shows a black screen. Im also in windows 10 , the exe also says that the calculator is connected but it is not running the program. Would be happy if someone helped me. Cheers!

EDIT: I found a chat system, calcnet chat, so that's covered. No wire connecting the 2 calculators is the goal though.

Me and my friend thought if you took the 2.5mm jack in a ti-84 silver with an adapter and hooked it to a bluetooth device and had that on two ti 84's, and used the send feature on (2nd) + link + a program with text in it, you could text in class. I know two students already did this, but something more compact and cheaper is what im looking for.
