<p>Since Texas I. probably paid off the collegeboard to allow the Ti-89, are there any advantages of the Ti-89 over a Ti-84 for SatI/IIs</p>
<p>As far as i know, theres no significant advantage of using the 89 over the 84, for both tests. The most youll do for math II is simple trig and precalc, so even an 84would suffice. IMO id just use the calculator you’re more familiar with and fast with.</p>
