But I don't understand what kind of movement I need to parametrize. can someone clarify the bugs movement in non-mathematical terms. Is the wheel moving in any dimension or just spinning?

The question is, if I parametrize the circle created by the intersection of the unit sphere with this plane, will that describe the intersection of the two spheres?SpaceManSpiffTue, 01 Jul 2014 09:43:05 -0500http://calc3.askbot.com/question/36/
