<p>I'm really confused with the disc/washer/shell methods. Is there a TI 89 program that will give me the integral for the volume if I type in the equations it's bounded by and the axis of rotation?</p>
<p>i dont think so. i think u just have to know the formulas and use the calculator to take the integral
those are really fun to do tho ^.^</p>
<p>Check ticalc.org if you haven't already.</p>
<p>come on now! why not try to understand where the formulas come from and then the set up is easy? Get some conceptual understanding :-) A good place to look is <a href="http://www.slu.edu/classes/maymk/banchoff/VolumeOfRevolution.">Volumes of solids of revolution</a></p>
<p>oops, sorry I messed up the link
