<p>Where do you get these programs from? Just googling?</p>
<p>Why do you guys cheat by trying to put programs on your calculator @<a href="mailto:@">@</a>. it's not even a freakin hard test. I wasn't even in pre-calc when I took it and recieved a 750.... you guys worry FAR too much and you really shouldn't just go downloading programs onto your calc. thats cheating.</p>
<p>no its not, lol even my teacher said that they WANT us to take advantages of our calcs, besides ti-89 has pretty much everything u ll ever need built in...From factoring to solving to trig, to w.e...</p>
<p>Yea sure w/e. They should ban everything 84 and up and not let 83 plusses.</p>
<p>89s are awesome.</p>
