<p>Hello!</p>
<p>I have been used TI 84 plus but it recently I broke it down (I was curious about its internal structure so I dissected it but in wrong way)...</p>
<p>My parents decided to buy me a good graphing calculator since I am going to take AP Calculus AB & BC along with AP Physics C. After some intense searching, I found out that TI CX CAS calculator and TI-84 Titanium are the best fit for the AP Cal. </p>
<p>Money is not really a problem this case because my parents are decided to buy me a lifetime graphing calculator. Which one should I buy? Also are graphing calculators from Casio also compatible?</p>
<p>I have a TI CX CAS and it is amazing – able to solve differential equations, indefinite integerals etc. I don’t even know how to use all the available functions on it lol</p>
<p>Ti-89 Titanium is the one I use and it’s a great calculator.</p>
<p>I would buy at least an NSpire (maybe NSpire CAS/CX) or TI-89. The graphics and interface on the 84 are poor, plus it runs slowly. The main advantage of the 84 is the programming capability.</p>
<p>Is TI Nspire CX CAS the current calculator from Texas Instruments?</p>
<p>Do you have any ideas on Casio and other brands?</p>
<p>Yes, but most stores sell non-CAS and non-CX calculators as well. I have one of the blue NSpires, which I doubt they sell anymore.</p>
<p>I have a ti inspire cx. I love it. you can graph poler an parametric curves and it can be used on AP,SAT,ACT, and BI test. The cas can not be used on all test.</p>

<p>The regular NSpires can also do polar and parametric functions. The nice thing about the CX is that it does 3D graphs.</p>
<p>The NSpires, CAS/CX, 89, and Casio can be used on any exam that permits calculators. The exception is that the ACT bans all CAS calculators.</p>
<p>Is there any big difference between CX and CAS? I want to buy Nspire CX but just want to know if CAS has a good program that outstands CX one?</p>
<p>CX has a color screen and can display 3D graphs.</p>
<p>CAS (computer algebra system) can solve equations algebraically (e.g. x^3 + 3y = 0 for y), evaluate indefinite integrals and limits, and has many other functions that the regular graphing calculators don’t have.</p>
<p>Of course, there are also CAS CX calculators.</p>
