The TI-84 Plus is a graphing calculator made by Texas Instruments which was released in early 2004. There is no original TI-84, only the TI-84 Plus, the TI-84 Plus Silver Edition models, and the TI-84 Plus CE. The TI-84 Plus is an enhanced version of the TI-83 Plus. The key-by-key correspondence is relatively the same, but the 84 features some improved hardware. The archive (ROM) is about 3 times as large, and CPU about 2.5 times as fast (over the TI-83 and TI-83 Plus). A USB port and built-in clock functionality were also added. The USB port on the TI-84 Plus series is USB On-The-Go compliant, similar to the next generation TI-Nspire calculator, which supports connecting to USB based data collection devices and probes, and supports device to device transfers over USB rather than over the serial link port.
I am not sure where to ask this question but I must try somewhere.

Hi,
I wasn't sure where to post this. I have a chemistry homework problem, which is not necessarily that hard, but it wants me to put values into my TI-84 Plus. I will not explain the problem too deeply, but it's about reaction time, volume, and concentration (mol/L).
I am given a table of...
I'm a college student and my old ti-84 plus silver edition just broke. I'm looking to get a new one that'll take me through discrete math, and advanced calculus classes. I'd like to get either the Ti-84 plus CE or the Ti-Nspire CX but I'm not sure of all the differences between them since it...
I had a student calculate ##\tan\left(\frac{5\pi}{6}\right)## on a TI-84 calculator and he had a rounding error in the 6th or 7th decimal place. This isn't really a big deal, but he asked and we quickly found out it was because he was in fraction display mode.
I don't know too much about...
Well the texas instruments ti-84 calculator is my favorite toy. I use it for anything I can from getting a girl to put her phone number in my calculator to programming.
Is there a way to somehow add an external circuit that can make the ti-84 send text messages. I bet there would have to be a...
Hi all,
I'm new to this forum and I'm wondering which calculator I should get. I'm planning on taking the ACT so I can't get (use) a Ti-89 titanium or a Ti-nspire CX CAS. I'll taking AP Chemistry, AP Calculus, AP Statistics, AP Biology, AP Physics, and AP Computer Science.
Thank You!
Is it possible to run TI-84 plus apps on the TI-84 plus C silver edition? If so, how do you do it? I'm not trying to run games or anything, just regular old apps.
When I try to send the files to my device I get an error message.
Hello I have a TI-84 Plus calculator and during my math class we were doing log functions on the calculator and I was met with the err "Argument". I don't know what this means, but from what I've heard my calculator is missing the required software to run a log. I should clarify that when I say...
Hello,
I need help using my TI 84 to figure out this 4 part question. My professor went over it way to quickly in class, when showing us how to do it on the TI 84, I believe its only a few quick steps for each part though.
EDIT: I have figured out part d, but am still struggling with parts a...
Hello,
I'm not sure if this is the correct section to post this in, but I need some help with my graphing calculator. I also posted this in the Statistics section.
I am given a set of X and Y data (2 sets of numeric data) and I need to find out how to find the Sxx, Syy, and Sxy in my TI84...
I need a new calculator for Highschool. I am looking at either the TI-84 Plus Color Silver Edition, TI-89 Titanium or the TI-Nspire CX CAS. I plane to major in computer sciences and become a programmer so I am looking for a calculator that is good for programming. Thank you.
Graphing Calculator---worth it?
I plan on majoring in either computer engineering or electrical engineering (have yet to take any related classes, so we'll see how long that lasts) and my calculus 1 teacher recommends that we have a ti-83 or 84 (made it through precalc with a B without it), but...
Hi.
So, for the first time my younger sibling will need a graphing calculator for their classes so I'm giving them my TI-84 Plus and getting myself a new, better one. Right now I'm a Junior in high school taking ap-chemistry, ap-physics and ap-calculus AB. Next year I'll be taking calc BC (my...
When I try and graph x^(2/3) in my TI-89, it only graphs the half of the graph where x>0.
My TI-84 gives me this:
But my TI-89 only gives me the right half. Is one of my settings wrong?
Here's what I want to do on the calculator.
1) Input sets of numbers, for example 3,6,9... in any notation, for example {3,6,9,infinity} or {x|x/3 >= 1 >= infinity}
2) use set theory (not now, but when I get into pre-cal/college.)
I have been trying to figure out how to plot a differential equation using my TI Nspire with very little luck. I managed to find that I can set the graph of the calculator to a directional field but I am not 100% sure I am getting the right results. So I figured I would ask to see if anyone here...
Something I've noticed that no one has ever been able to sufficiently explain to me is taking the sin of multiples of 2-pi.
Sin 6pi, 8pi, 12pi. You get silly answers. For example, sin(6pi) gives you -4*10^-13 instead of 0. I've never been able to get a satisfactory explanation. Most people...
It's simple.
1. Press the Y= key.
2. For Y1, enter the left side of the equation.
3. For Y2, enter the right side of the equation.
Note: You have to write the equations so that x + y = 7 becomes y = 7 - x or 2x + 4y = 10 becomes y = (10-2x)/4. You can only have one independent...
I'm currently attempting to design a program on my ti-84 calculator (ti-nspire w/ 84 faceplate) to provide an approximation of the sin(x^2) as accurate as I would like the sum the reach. I attempted to input a formula for such, sum(seq((-1)^(Z-1)*X^(4Z-2)/(2Z-1)!, Z, 1, n, 1)), "Z" being the...
Unless I'm missing something here, I've noticed that if you want to store a polynomial function on the TI-83 or the TI-84 Plus, you have to create a program that asks you what the value of x is, then displays the value of f(x). I kind of wish I could define a function without making a program.
When some people explain how to do a certain calculation through a presentation, I sometimes see these presentations use the buttons necessary to press as pictures. For example, I've seen presentations tell me how to graph certain functions and, instead of saying press "Y=," the presentation...
TI-84 HELP!
The formulas under the CONICS app keeps converting into trig... It saying a circle is
x=rcos(T) + H instead of (x-h)^2 + (y-k)^2 = r^2
How do I get the 'normal' formulas back?
PLEASE HELP!
I'm taking an online "Elementary Algebra" class from my local community college. It's been a few years since I graduated high school and I've forgotten pretty much everything; including my T-84 Silver, which I never took full advantage of its potential anyway.

Anyone know any better way?
I wasn't sure where to lost this thread so I decided to put it in general discussion. So anyway, on my TI-84 graphing calculator I have been having this weird problem, once in a while a setting will change on its own( not sure how) and then the calculator would stop letting me graph...

2. Should I get a TI 89 or a TI 89 Titanium? I've...
Hi,
I am pretty good with my calculator, but I am beginning to notice that my ti-89 titanium has many features that I am not making use of when I am working on my physics HW or exams. I am not talking about programs that can be downloaded, but the built-in features.
I am wondering if...
