<p>to ask if any of you math wizards have actually used the Calculus Made Easy from ti-89.com?</p>
<p>While I’m at it, any opinions of the TI-89 vs TI-NSpire (screen size, teaching modules, SAT prep questions)?</p>
<p>Our S finds math challenging, and we’re trying to find “step by step” TI software which explains very clearly math subjects: algebra, trig and pre-calc maybe calculus as a backup while doing homework problems.</p>
<p>I’m just checking out ticalc.org as well as the student site at TI itself which is now pushing the Nspire.</p>
<p>Thanks.</p>
