I want to know how from fundamental motion we can write out a parametrization equation and with that find a line tangent to that point. *Comment*: Does this refer to a particular problem?asmith14Mon, 30 Jun 2014 17:57:28 -0500http://calc3.askbot.com/question/30/http://calc3.askbot.com/question/19/the-bug-on-the-wheel-goes-round-and-round/I'm pretty confident that I understand how to parametrize the bug's movement. 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?
