Rules

my ti-84 calculator's buttons work but you have to click really hard for them to register and sometimes they'll register twice (aka clicking 2 would input 22)

all the number buttons are affected and this is really inconvenient for timed tests and live lectures... i already tried spraying compressed air to no avail. does anyone know how to fix this?

I'm trying to write the Ruffini step to find P, but I'm having a problem. If I do -2^2 I get -2, and if I do (-2)^2 it's 2. All this to say that this is the function I'm writing:
p(x,m):=∑(x[dim(x)-n+1]*m^(dim(x)-n+1),n,1,dim(x))

Here, m is elevated to the nth power. The problem is that this doesn't account for the number's sign. It's always negative. I tried putting it in parentheses, but when I press enter thet get deleted. What can I do?

I recently tried to get TiBoy on my calculator with cesium and artifice but it just gave me an error when I tried to open the program. It just says TiBoyDat Missing.

After I enter the expression or equation I want to evaluate in the calculator and I press the "Menu" button – then under "Algebra" there should be the item "Show Steps" but it's missing on my calculator.

Does anyone know what to do or how to get that?

Software version is the latest.

As the title implies, does such an app exists / could it be possible? I *think* TI has LaTeX built in on normal mode, how can this be implemented with cesium? Would you have to implement it as a font?

Please give any and all thoughts

EDIT: I mean as a notes thing, like text editor CE

Before requesting help with problems that you may be experiencing with your calculator, try these things first! You might save yourself some time.

If your calculator is giving you unexpected answers...

Check the settings.

• Check to see if any settings are changing the format of the results. (NORM, SCI, ENG) will affect how results are displayed, and (FLOAT, FIX #) will affect the number of decimal places your result will have.
• If your problem involves trigonometric functions, such as sine and cosine: check your angle settings. You may be in degrees instead of radians or vice versa.
• Check the number mode. (REAL, a+bi, re^(ϴi)) are used for calculations involving imaginary numbers.

If your calculator is giving you unexpected errors...

• If your problem has a negative number, you need to use the "(-)" button to indicate to the calculator that the number is negative, and not the subtraction sign.
• If you are graphing, check if any "plots" are on. It's easy to accidentally enable the plots, so make sure that Plot1, Plot2 and Plot3 are not highlighted.
• Also check the function type that you are using (FUNCTION, PARAMETRIC, POLAR, SEQ) if you aren't able to graph correctly.

If you're not able to use MathPrint...

Either your calculator doesn't support it, or you have the feature disabled.

• MathPrint is only available on the TI-84 Plus and later, the nSpire line and the TI-30XS or later.
• Make sure the option to use it (CLASSIC, MATHPRINT) is enabled.
• If you don't see the option, but are using a TI-84 Plus, you'll need an OS upgrade. Look for "2.55MP," then use TI Connect CE to transfer the OS.

If your TI-84 Plus CE will not power on...

This is a common problem related to the battery.

• For now, your best option is to purchase a replacement battery.
• You may be able to use the TI CARES helpline for assistance in getting a free replacement.

If your calculator is still malfunctioning...

Try the following steps.

• Reset the memory. There are different methods that can be used to reset the calculator, from the reset button, to key combinations, to removing the batteries for some time. You will need to do some research to find the key combinations for your model of calculator.
• If possible, try new batteries. Although many calculators are able to warn you if a replacement is needed, there are some that can't. This may solve your problem, especially with scientific calculators that are able to use solar power.
• Send a new operating system. TI Connect can install operating systems to your calculator, but there are alternative options if you need them. Some calculators can also transfer operating systems to another.
• If test mode is enabled, sending any file to the calculator will put it back to working order. Test mode will also drain your calculator's batteries faster, so make sure to turn it off!

Hi all,

Just wondering if anyone had any way to convert a CSV file to a TNS file (for students to do data analytics on) while maintaining the integrity of the original spreadsheet?

Help much appreciated :)

When putting i to a power that would result in 1 or -1 I get this instead while my classmates or regular ti84 plus calculators get the regular number is there a way to change this or it his just how it’s displayed on this calculator (im not in scientific mode if that matters)

For some reason, the display on my calculator is all messed up and slanted. It's running MirageOS and runs Doom just fine. Thing is, it's been like this after like 6 tries of redownloading it. I asked ChatGPT and did some searching but nothing I can find so far is fixing it. I'm using the TI Connect link cable (USB edition) and I'm using the TI Connect software to get games and MirageOS on there. I tried Ion, but that must be upgraded for something more like the TI-84 Plus (maybe CE) now. That and Tetris both run like crap, with the blocks in Tetris crossing the screen vertically once and stopping around the middle. This is weird.

Here's what the issue looks like.

I'm trying to program a game, and I need to put in this symbol "->," which is a right arrow. I cannot figure out how to input this into my program, please someone help me

So I want the program I'm writing in tibasic to ask me which variable to store a calculated value to. I figured this would work, but it doesn't.

:Input " enter var ",Str1

(then enter A or something)

:1+1→expr(Str1)

Hello!

I wanted to ask if you know any way to display the solution step by step (respectively show steps) on the TI-Nspire CX II-T CAS?

I have already done some research and supposedly this should be possible via Menu --> Algebra --> Show Steps

For whatever reason, I don't have this option on my calculator...

My question relates to the following mathematical topics:

Algebra, (differential) equations, fractions, brackets, simplification of terms

Trigonometry

Thank you so much!

my nspire cx is powering on when plugged in but doesn't seem to be charging, does anyone know why? it has a warning symbol over the battery indicator

I want to plot 4 lines, lets say
x = 2, cuberoot(y)
y = 8, 0
I found out that you can add a "x =" variable for plotting by pressing apps>Inequalz.

Now I'm stuck on how to add a variable y in the "x =" portion of the graph.

Sorry I am really new to Graphic Calculator. I'm just using it purely to plot graphs

I bought a new TI 84 plus CE on ebay. It didn't say anything but when it arrived it was python edition. I'm an engineering student. Are the functions or anything else different? Can I jailbreak this thing?

( i use this plan: https://www.ticalc.org/hardware/cables/serial.html) Well... It dosent work, I suspect that the 2.5mm pług is too short. I use tilp 2 and my serial to USB converter works well, my calculator slows down when i pług my cable im (it has very big latency while pressing keys) can someone help? I use a ti-82 stats

How do I put a title in the grey spot when using the Text command? Like in the picture.

I just got a TI 84 and when i plug in to charge It turns on says validating os, turns off, turns back on for like a second and turns off. This cycle keeps repeating and I don’t know if it’s a power problem or something else. The reason i think it is a power problem is because it keeps turning on and off. This might be because it isn’t receiving enough power and doesnt charge enough to stay on. Please help!

I wanted to play some ti-84 games on my ti-nspire with 84 plus keypad, but I am having trouble running basic apps on it, can anyone help me?

Hello, I have a TI-89 titanium and I want to put EE*Pro on it. The TI website goes to a dead form and no email is ever received. Can someone offer another location to download this app? This software is free so this should not be an issue.

I have a TI-Nspire CX II CAS. When I type ∛16x^5 I get 2*2^1/3 *x^5/3, but I would like to get 2x ∛2x^2. Is it possible to get that answer?

Got a TI-89 titanium on FB marketplace. Screen works great, but some buttons don’t work. I opened it and it has a corroded motherboard. Already tried de-oxit and vinegar. Is this beyond saving?

I charge my ti 84 plus cet python with my PC only. When i plug it out, it doesnt have a sign of charging and the PC disconnects it. Will my calculator charge while its screen is turned off?

My brand new ti 84 ce+ only works when plugged in even if charge is shown to be full.

found an old TI89 in my parents garage, NOT the Titanium version, it still powers on but is permanently stuck, can only turn it off by removing the batteries, I've tried changing them including the back up one but that didn't work, i left it empty for a couple of days and that didn't help either, I searched around and it looks like the OS is corrupted.

It seems you can fix it by re-installing the OS using the TI-Connect app but I don't have the silver cable that is used to connect the calculator to the PC, it seems like a standard 2.5mm to USB Serial but the silver cable has a PCB in the middle of the cable and I'm not sure if that is necessary for it to work.

My question here is, do specifically need the TI-Connect Cable/Silver Cable to connect the calculator to the PC? Or can I use a standard 2.5mm to serial cable to fix the calculator? Are there alternatives? Asking cause the cables seem to be more expensive than the calculator itself lol.

Thanks beforehand

If I input a division problem using only whole numbers, it will only give an answer as a whole number, fraction, or equation. I need it to give exact decimals. For example, if I input 5/2, it will return 5/2. However, if I type in 4.4/4, it will return 1.1. If I input sqrt(4628), it will return 2*sqrt(1157)
