<p>Is it necessary to have one for class? I'm debating as to whether I should buy a ti-89 or not. I only rented one for my calculus class in high school, and all I have is a ti-84, which can't really do anything...</p>

<p>[Wolfram|Alpha—Computational</a> Knowledge Engine](<a href=“http://www.wolframalpha.com%5DWolfram%7CAlpha—Computational”>http://www.wolframalpha.com) - best public free calculator that I know of. :)</p>

<p>TI84 is good enough, but TI89 is really useful when it comes to doing derivatives/integrals. The only way I could see you buying a TI89 is if all your exams allowed you to use a calculator on them and if they do then I would buy it since it has a significant advantage over the TI84.</p>

<p>Also if you have an iPhone/iPod touch there are some nifty programs like Wolfram Alpha or other graphing calculators that are either free or less than $10.</p>

<p>You’re doing it wrong…</p>

<p>I would suggest one of [url="<a href="http://www.calculatorsbest.com/images/pictures/sharp-el531wbbl-translucent-blue-scientific-calculator.jpg"]these[/url"&gt;http://www.calculatorsbest.com/images/pictures/sharp-el531wbbl-translucent-blue-scientific-calculator.jpg"]these[/url</a>].</p>

<p>Do a lot of the math profs not allow calculators on exams?</p>

<p>The last time I was allowed a graphing calculator on a math exam was AP Calc.</p>

^ lol, yea, so true. Math profs usually dont allow graphing calculators on exams. If you do need calculator, they sometimes only permit scientific calculators.</p>

<p>I don’t think I’ve been allowed any sort of calculator in any of the math or physics classes I’ve taken (and they usually wouldn’t be all that useful anyway). We were allowed any type of calculator in Chem 20A, but even a 4 function calculator probably would’ve been sufficient there.</p>
