Ti-83 Definition and 68 Threads

I think the solution should be: METHOD #1: \begin{align} (\sqrt[4] {-1})^4 & = (-1)^{\frac 4 4} \nonumber \\ & = (-1)^1 \text{, can reduce 4/4 since base is a constant and not a variable in ℝ} \nonumber \\ & = -1 \nonumber \end{align} Alternatively, METHOD #2 for same answer is...

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 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 won't allow a CAS capable calculator, and that you can get the interchangable keyboards to remove that...

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...

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'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!

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.

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?

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?

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...

(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...

A ton of water got into it. Now the display is messed up but only so that I can't see the bottom line.

TI-89 "PAY" program, infinite loop problem? I have tried to write a program required for class (Math Analysis, junior in high school, 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...

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...

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...

[SIZE="3"][FONT="Times New Roman"]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...

I just got my Staples ad for the coming week via email, and saw they have advertised for two days only (Aug 23 and 24) TI-84 graphing calculators for $79.99 after rebate. No, I do not own, work for, or have stock in Staples...but this is the lowest price I have ever seen for this graphing...

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.

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...

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...

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...

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...

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

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...

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...

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!

Need Help with my TI-83 Plus PLEASE! i got my TI 83 plus, and yesterday went out to by the cable so that i can get programs for physics n stuff onto it, but after i downloaded the program, i dragged n dropped it into the TI connect icon to transfer it. it transfered, but the program wasnt on my...

I got mine recently, I haven't 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...

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...

My professor today told the class(engineering statics) that we should invest in the ti-89 or an equivelant. He claimed that the ti-83 was good for middle school but not for University work. However, I was forced to buy a ti-83 because the math department at my school doesn't allow anything...

I have a TI-83 graphing calculator and am thinking about upgrading to the 89 because extra useful features. Is it worth it?

Hello everyone, sometimes it's easier for me to run calculations on my computer rather than to go find my graphing calculator. Are there programs out there that have all the functions (or more) of my graphing calculator (TI-83+). Also if anyone knows of any good like bluetooth keypads to...

Hey all. I'm a freshman in college. I'm in the Computer Science BS course, and am just about to start our 2nd semester. According to my suggested scheduling for my course I will be taking Tech Math II, Calc 1, Calc 2, and Differential Equations. I do not own a graphic calculator, and...

Just a quick question about the Ti-83+ calculator. After you have hit the equals button to provide the solution for an equation, how do you get back into the equation to make any changes? The error key is not what I'm looking for, is it possible to make any changes you want in the equation? I...

I have a TI-83 that I got way back in high school. My best guess is that it is from 1997. Given the huge advance in computing technology, is there any good reason to upgrade itr? Do the new ones have significantly better performance? significantly better features?

1. After I launch the "Home" program and enter d(x^2,x) The calculator spits out -52.4916, a numerical solution. What I want is the algebraic derivative 2x - how do I get to the algebraic derivative? 2. When I enter sin(60), it gives me -0.304811 as an output. Why does the Ti-89 give a...

Why won't my Graphing Calculator link with my computer?? ok here is the breakdown... I am running windows XP on my computer i installed the program last nite (with some help from you guys) and was really excited to start working with it but for some reason the graphing calculator(TI-83+) won't...
