This isn't quite a homework question, but my calculus teacher mentioned to those of us also taking physics that it was possible to prove that I = .5MR^2 using calc. I had some extra time on my hands and decided to give it a try. I've tried doing a summation with a geometric series but then ran into trouble defining a and r [using the equation a/(1-r)]. Does anyone out there know how to do this?(adsbygoogle = window.adsbygoogle || []).push({});
