According to Surely You're Joking, Mr. Feynman, Feynman said that he had studied a bit from Calculus for the Practical Man, and when he started to goof off in his high school physics class, his teacher gave him Advanced Calculus by Woods. It's on page 86 in case you have it.

Excellent Thanks everyone. You guys all gave good examples, and I understand it now.

Hi. I recently started learning physics on my own, and I'm having a bit of a problem with the concept of tension. That is, I'm not exactly sure what it is. In the textbook I bought, tension is defined a bit hastility in a section entitled "Applications of Newton's Laws." I grasped the...

Excellent Thank you very much, that cleared up everything. For some really odd reason I didn't use an equation which factored in acceleration, and instead used an equation which assumed constant velocity (t = 2piR / v). Thanks again for clearing things up.

Hmm Perhaps I missed something, but shouldn't that be vT = 2 * pi * r ? I'm not really sure where the (1/2) came from on the LHS, which is possibly why I keep on coming up with x = arctan 1 / ( 2 * pi) instead of x = arctan 1 / (4 * pi). Could someone please elaborate?
