<p>any one try this yet? I'm contemplating buying one but im havent really found any helpful reviews any comments would be of great help thanks!</p>
<p>i didn't try it personally, but my calculus teacher went to a whole workshop on the Ti-Nspire and she says it has quite a few kinks. She recommended that we wait till they work them all out, and she said she definitely preferred her Ti-89. =D</p>
<p>Its really nice. This guy at TI let me use it when he was showcaing it. It seems worth it and the same price as a TI 89</p>
<p>we had a TI sales person come to our math club meeting, they seem ok but they havent perfected them yet. we got to use them too its a hassle to keep taking the keypads off.</p>
<p>No keypad for the CAS one. The CAS is like an 89 but much better user interface and has some other sstuff added too. Serioulsy it is like a computer. Its got something like a mouse with a clicker on the calc.</p>
<p>my calculus teacher helped develop it</p>
<p>Can someone please tell me the difference between CAS and non-CAS calculators?</p>
<p>WHat do you mean? CAS just stands for computer algebra sysstem which is just very legenat math software that can be used to do a veriety of things. Here I looked some of it up for you</p>
<pre><code>* simplification to the smallest possible expression or some standard form, including automatic simplification with assumptions and simplification with constraints
* substitution of symbolic, functors or numeric values for expressions
* change of form of expressions: expanding products and powers, rewriting as partial fractions, constraint satisfaction, rewriting trigonometric functions as exponentials, etc.
* partial and total differentiation
* symbolic constrained and unconstrained global optimization
* partial and full factorization
* solution of linear and some non-linear equations over various domains
* solution of some differential and difference equations
* taking some limits
* some indefinite and definite integration, including multidimensional integrals
* integral transforms
* arbitrary precision numeric operations
* Series operations such as expansion, summation and products
* matrix operations including products, inverses, etc.
* display of mathematical expressions in two-dimensional mathematical form, often using typesetting systems similar to TeX (see also Prettyprint)
* evaluating to high precision (bignum arithmetic). For instance, allowing the evaluation of 21/3 to 10,000 digits
* add-ons for use in applied mathematics such as physics packages for physical computation
* plotting graphs and parametric plots of functions in two and three dimensions, and animating them
* APIs for linking it on an external program such as a database, or using in a programming language to use the computer algebra system
* drawing charts and diagrams
* string manipulation such as matching and searching
* statistical computation
* Theorem proving and verification
* graphic production and editing such as CGI and signal processing as image processing
* sound synthesis

<p>These calulators won't be aloowed on most tests though. SO I WOULDN"T GET THE TI_NSPIRE CAS. It doesn't have the additional keyboard. Calc I and Cal 2 would lose their points if it differentiates for you. Linear Algebra is very abstract and you will fall behing if you take it using your calculator to do all matrix operations for you.</p>
<p>If you really want a CAS get one for your computer like Mathematica. Our school and a local college is hooking us up with free copies of it (it costs $2500)</p>
<p>I'm not worried about falling behind in math when I get to college, hence why I also have a TI-84, and I'm not looking for a computer based CAS because I already have a personal copy of MATLAB that I use for work, plus I already talked to my teachers about it both physics and math and both supply a non calculator open response and the calculator part is only multi choice so I'm fine thanks for the concerns though</p>
