1. The problem statement, all variables and given/known data Take the Inverse Laplace Transform of F(s) where F(s)=((s)(tan-1(1/s))) 2. Relevant equations 3. The attempt at a solution i know that f(t)=L-1(F(s))=(-1/t)L-1(F'(s)) and d/ds(1/tan-1(x))=1/x^2 +1 but the example i'm given with an inverse laplace of tan-1 is way prettier than this problem. hint?
