1. ### Calculators Graphing Calculator-worth it?

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...
2. ### Calculators TI Nspire or Casio Prizm

Hi all, I know this is very subjective and probably ask a few hundred thousand times. I'm an mech engineering student looking to upgrade from my ti 83. I know atleast so far my math classes wont allow a CAS capable calculator, and that you can get the interchangable keyboards to remove that...
3. ### TI Nspire or Casio Prizm

Hi all, I know this is very subjective and probably asked a few hundred thousand times. I'm an Mechanical Engineering student looking to upgrade from my ti 83. I know atleast so far my math classes (Calc II) wont allow a CAS capable calculator, and that you can get the interchangable...
4. ### Calculators TI-83/84 sets of numbers/set theory

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.)
5. ### Calculators Vector capable calculator recommendations?

I'm taking a vector analysis course this semester and would like a vector capable calculator. For calculus I have been using a TI-83. Any recommendations? Price not an issue, but as always its better to get the job done for less. Thanks!
6. ### Calculators TI-83/84 Plus - Storing polynomial functions

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.
7. ### Calculators (-i)^4 = Domain Error?

I'm curious if anyone knows why my calculator would return "Domain Error" when calculating (-i)^4 on my TI-36X Pro? ((-i)^2)^2 works just fine on the machine, and (-i)^4 works just fine on my TI-83 Plus. Any ideas?
8. ### Calculators Calculator giving weird answers?

For sin(4pi), my calculator gives -2^-13. Obviously, that is really close to the correct value of 0, but it just says 0 for ANY other multiple of pi I've tried. Weird right? TI-83 plus.. common calculator. Anyone have issues like this?
9. ### Calculators Slope Field Program for TI 83

Hi I was searching for a slope field program for my calculator and found this one http://www.math.lsa.umich.edu/courses/116/Calculator/TI83/TI83-SF.html for some reason I can't get it to work. When I run it I only get one line row of lines at the bottom of my window when it graphs it. I...
10. ### Calculators Good non-graphing calculator

(Not sure where to post this, so please feel free to relocate if needed) I am hoping someone can give me some advice on a good calculator for my Calculus class. I am currently using my trusty TI-83+ as my go to device, but my instructor will not let us use any graphing utilities on the test...
11. ### Calculators How do I repair my TI-83?

A ton of water got into it. Now the display is messed up but only so that I can't see the bottom line.
12. ### Calculators TI-89 PAY program, infinite loop problem?

TI-89 "PAY" program, infinite loop problem? I have tried to write a program required for class (Math Analysis, junior in highschool, everyone else has an 83 or 82 but my grandmother bought me this one......so nobody else has been able to help yet) but after solving one error message (I had to...
13. ### Calculators New calculator?

Hi there I'm doing a double degree in physics and mech engineering. Up until now, I've been using my good old Ti-83 and has served me well but me thinks it may be time to maybe invest in a good calculator for the future. I would prefer to stay with the TI brand since I'm very...
14. ### Calculators Which graphing calculator to buy? approved for the SAT, ACT, AP

I'm currently taking a high-school pre-calculus class and next year I'm going to be taking AP Calculus and Physics I. I plan to major in Physics in college and I'm looking for a calculator that will get me through all of that. I need one that's approved for the SAT, ACT, AP, and is powerful...
15. ### Best Beginner Programming Language?

I am looking to start learning programming more or less on my own. I can make some advanced programs on the TI-83+ calculator and have been for the past year. I learned just from reading the manual and messing with the different logic operators and commands. What are some good beginner...
17. ### The fraction function on calculators

My TI 83 plus has a function called "Frac" which makes decimal numbers into fractions. If I have 0.33333... on the screen and press Frac the calculator returns 1/3. My question is how does this function work.
18. ### Calculators Sequences, Cumulative Sums, Partial Sums Plot - Ti-89 Titanium

Sequences, Cumulative Sums, Partial Sums Plot --- Ti-89 Titanium My proffessor just gave us all these packets for all these programs he wants us to put into our calculators. They are for a Partial Sums Plot, and a List of Cumulative Sums, nth terms and differences. They're all for the Ti-83...
19. ### Calculators Where to get large display (Like TI-83) calulator that is non-programmable?

My Fluid Mechanics teacher doesn't allow programmable calculators and he checks before the exam. I asked him and he said we can have any large display calculator as long as it isn't programmable. Has anyone seen such a thing? I really am dependent on the giant LCD that shows the equation after I...
20. ### Graphing y=x

I am new to Matlab and i need to plot a function. However, using y=x as an example it always comes up saying that x is not defined. How do i plot the function without specifying a specific value for x? Graphing y=x is not my real problem. I am used to using TI-83/4 graphics calculators and...
21. ### TI-83+ Games and Programs

This game is where you try to hit a target on the ground, very simple but addicting. Called Arcshot, I did not make this, I found it on the web and though it was fun so i put it here for others. Key: -> is Sto < or > is less than or more than * is times ^ is a carrot If you can't find...
22. ### Calculators How do I add games to my TI-83 Plus Silver?

How do I add games to my TI-83 Plus Silver? Are there any instructions on how to add them? How do I play them once they are on my calculator? I lost my calculator software drivers CD, and I don't recall what else was on that CD. Could I get another copy of the CD online for freeware? If so...
23. ### Are there any Texas Instruments forums?

Hi everyone, Are there any such forums for Texas Instruments such as (TI-83 Plus Silver) calculator forums? Do they have direct main forums?
24. ### TI 83 Problem

I have a TI 83 Plus, and i wanted to put some programs on my calculator. But the problem is, every time i install my TI connect software and Graph Link, and connect my calculator, it says that the driver not found. no matter what i do, it always says that driver not found. I go in the TI connect...

How come the 89 is more expensive than the 89 Titanium on Amazon? https://www.amazon.com/dp/B0001EMLZ2/?tag=pfamazon01-20 https://www.amazon.com/dp/B00000JF55/?tag=pfamazon01-20 Isnt the Titanium a lot better?? Are there a lot of differences between the 89 models and the Ti 83? Are...
26. ### Is the TI 89 still useful or not?

I am a first year Petroleum Engineering student and I currently use a TI 83+. However, the TI 89 comes recommended from my math professor and TA. I have two questions: 1. Should I get one? It is that much more useful? How so? Pros and cons? 2. Should I get a TI 89 or a TI 89 Titanium? I've...
27. ### Calculators Ti-NSpire or TI-89

Has anyone had a chance to use this new model? Also, if I bought the Ti-Nspire, would the CAS version be more useful? I need to purchase a new calculator for the fall, which would you recommend? I currently have a TI-83 Plus. Thanks!

29. ### Calculators Questions about a TI-89

I got mine recently, I havent used it as much, because I still have a TI-83, someone told me that with a 89 you can store equations, notes and it shows all of your work? Is that true, because I heard this from two different individual, and a third person told me that it doesn't show all of your...
30. ### Calculators TI-89 and HP 50G?

The main difference between the two (other than the RPN which I don't care much about as I am already used to using a TI-83 which doesn't have RPN) is that the HP is powerful, and the TI has more 3rd Party support. Of that though, the things I care about most is that you can expand the memory of...
