<p>…TI-89 and TI-89T? Can I do everything Mathematica can do on here?</p>
<p>The diffrence is processer power ad memory. For calculating partial sums and numerical integrals the titanium is a lot faster. the software is the same though</p>
<p>Buy the Titanium - symbolic integration and DiffEq, slope fields, etc. Plus it’s awesome (I have it and love it)!</p>
<p>I bought it almost two weeks ago. I don’t know how to use it.</p>
<p>I still use a TI-83+ s.e. from 8th grade :(</p>
<p>I still use a TI-85 which my sister used when she was in Calculus 10 years ago.</p>
<p>Non-titanium does all those things too Alexandre…</p>
