HI y'all! I was just told by my programming teacher that I need a new graphing calculator. She told me to decide between the TI 89, Casio Classpad fx-cp400 (or fx cp500) or the TI-Nspire CX C.A.S. I don't know if greyscale or color matters though in the long run. I am a programmer and need...

Hey so I'm new to my TI nspire cx, still getting the hang of it. I've been trying to figure out how to get my eigenvector values to be fractions instead of decimals when I calculate them on here. Also, when I find the polynomial roots I get back decimals instead of fractions. I would like to...

Hello everyone. I am going to be purchasing a good graphing calculator soon. That being said, I will hopefully be going to college to get a degree in aeronautical engineering. So what do you all think is the best of those calculators? I have been leaning towards the Casio CP400 because of the...

Sorry, title limited on what I could type. I just got this calculator and am having two big issues with it. 1) I cannot figure out how to reuse my most recently typed equation. For example if I type in a insanely long multiple variable equation and evaluate, the only way I can figure out how...

My CAS screen cracked. Can I move the CAS motherboard to another CX I have?

Hi and thanks for reading. I am looking for a calculator to use purely in exam or tutorial situations where I don't have access to a computer and need to solve algebra problems (usually hydraulics (mannings, specific energy equations solving for flow depth) or geotech related) where the...

I have just gotten my new Ti-nspire CAS calculator and seem to be stumped. I have created my two equations from my mesh analysis of a circuit. Loop I2: I1(2+j2)+I2(8-j2)=12 Loop I1: I1(-j2)+I2(j-4)=0 I know I can solve this by hand but would like to learn to use my nspire. Any direction...

Hi guys, I am a freshman engineering student and recently bought a ti nspire for my calculus based physics class. The teacher strongly recommends getting programs for his class on our calculators to make our lives a lot easier. I've been looking everywhere for programs for like centripetal...

Hello, I have a question about if it is possible to get interval notation on the TI Nspire CX CAS. If so how do you do it? Thank you

Hello physics community, I am about to start my university studies and I am wondering which calculator to buy, a: TI-Nspire CX graphing calculator, Casio fX-CG20 graphing calculator or an HP 75mhz, 2300 functor, 3-1/5"x7-1/5"x9/10" graphing calculator. I simply want the best of the best, the...

Graphing diff eq slope field with TI Nspire CX CAS HELP please!? Every time I try to graph a slope field an error message pops up saying 'wrong number of initial conditions'. What does this mean? I tried graphing equations like dy/dt = t^(2) + t or dy/dt = 1-2y but I keep getting that dumb...

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.

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...

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...

Hi guys Can I calculate phasors in a ti cx cas as simple like in a ti 89. In a few days I will need to calculate them in a test, so I need to buy a ti nspire cx cas or ti 89. I think ti inspire cx cas can manage ecuaciones with complex like 89 does, but I can't find how to calculate phasor...

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...

Hi. I'm going to university in a month to study Electrical Engineering.I already have an TI83 + , but I'm thinking of upgrading to a TI 89 or TI Nspire CAS CX because they both have CAS. Now from what I've read on the Internet the Nspire CAS seems better because of the higher resolution color...

Hi all - couldn't find another suitable place to post this on the Internet... My TI92 died last week after 15 years of use (OK I killed it with coffee), and I thought I'd just try and get by with Wolfram Alpha but it's just clunky and horrible. I'm currently using my spare TI86 which lacks a...

For undergraduate college, would you guys suggest purchasing a regular graphing calculator such as an HP 50g or TI-Nspire NX CAS, or something like Mathematica 8 for Students at the same price?

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...

Hi, I'm new here. I did some research plotting the ODE of y'=3+2y without having x shows up in the equation. I can't figure it out, why the calculator does plot a harder equation but not a simple one? I can get the slope field with an equation that has an x in it. However, without x, my...

So I've been shopping around for calculators for the past week or so and I stumbled upon this gem...I'm looking at its features and specifications and there's nothing on the surface that stands out to impress me. Compared to another model such as the 35s, why is this thing like $150? I'm also...

Anyone have the new TI calculator? My 89 is working perfectly, but it's so freaking slow in graphing the simplest surfaces. My only concern is the battery life. TI claims this new color doo-dad will last 2 weeks between charges. Provided that is true, that would mean that I would probably...

I had no idea where to post this. Anyways, I want to buy a graphing calculator. I am deciding between a Ti-89 Titanium and a Ti-Nspire CX. Or, is there another calculator you suggest? Right now I have a Ti-30XS, and I like the kind of logic used to enter my math into that. I don't like...

Hi, I'm looking at a few models but I'm having a hard job seeing if any/all of them have a sort of Physics equation solver. For example, laws of motion, a calculator that could tell me for a set of given values what the value of s is when t=2. Or, say, for a given velocity curve - show the...

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. So I went out and got myself a new...

How can i transfer a text document (word, pdf or text file) from PC to TI nspire CAS. I am lost and need help. I have install TI software on my PC. Thank you in advance for any help you can provide.

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 wasn't sure where to post this, as it's just a general question rather than anything actually math related.. I'm starting pre-calc this summer, excellerated, and going into calc 1 at the second half of the summer. This is to get me ready for starting my Physics major in the fall. I'm a...

Hello guys, I just bought TI-Nspire CAS+ graphing calculator, and I am wondering what are the differences between CAS+ and normal CAS. What are pros and cons? Thanks in advance, Jan

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!
