<p>My friend gave me a couple calculator programs for the Ti-84 that can do pretty much any problem. It can answer complex algebraic problems for any problem with less than 3 variables and can allegedly answer most geometric problems. Is it incredibly wrong to use these on standardized tests, or is it a crime that doesn't hurt anyone?</p>
<p>Go ahead and use them. There's nothing against using them. It's not a crime, it's not cheating. It's just another tool, like the calculator, to help you do well.</p>
<p>Well, it's legal, so it's not cheating...</p>
<p>I believe the question you're asking is whether it is morally correct? If so, than you know the answer.</p>
<p>As far as solving equations are concerned...most calculators such as the TI-89s do that already and they're allowed. TI-89s sometimes come with a Geometry app too and College Board doesn't care. And doesn't it say somewhere on the site that programs are allowed? Legally, it's fine, as darkburnout said. Morally, I'm not sure it's entirely wrong if college board says on their website that it's ok to use them. Just go and check under acceptable calculators.</p>
<p>If it wasn't allowed they would either not allow graphing calculators or make you delete programs before entering. If they don't have rules on it its definitely okay. I wouldn't have any ethical qualms about it at all. I definitely used my programs, although the IB forced me to later delete them.</p>
<p>i thought they delete your memory on the calculator before you enter</p>
<p>Nope they don't.</p>
<p>TI-89s basically have all of the functions you described and Collegeboard is still allowing TI-89's for SAT/PSAT/SAT II. There are no regulations against using those kinds of modules, but if you think it's against your morals or ethics then you're free to do whatever sets your mind at peace.</p>
<p>Personally though, I find no need for such modules on SAT math. Most of those programs only slows one down; not speed one up. A thorough understanding of the material is more essential than any kind of TI module out there.</p>
<p>does anyone know if the TI-89's can differentiate almost ANY type of calculus problem?</p>
<p>It can't implicitly differentiate, but otherwise I've been able to do everything else. (I'm in AP Calc BC now so if there's anything more advanced than that you're asking for, I wouldn't know).</p>

<p>Wrong.</p>
<p>f3:impDif(equation, independent variable, dependent variable [, order])</p>
<p>What are you talking about?</p>
<p>octalc0de, what's your OS? I'm pretty sure I have a 3.0 and that doesn't let me implicitly differentiate. Maybe later ones do.</p>
