Cot[] and Tan[] are periodically, so they don't have limits in Infinity. What I meant are above expressions with a->0°. I checked this, and this works in both cases (Limit is 1). The n in the second expressions is a typing error, of course it should be a. I promise this newsgroup to write a little bit more thoroughly in the future ;-) Oliver Friedrich
