Homework Help: Inverse Laplace Transformation of Inverse Tan function

  1. Nov 3, 2009 #1
    1. The problem statement, all variables and given/known data

    Take the Inverse Laplace Transform of F(s) where

    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?

    Well, the first thing to note is that

    Do you know the convolution theorem?

    Also, if you're not going to use latex, please use the "sup" and "sub" buttons (they're the buttons that look like [tex]\text{X}^2[/tex] and [tex]\text{X}_2[/tex]). And make sure you use parentheses for the denominators of fractions. That said, I highly recommend you learn at least some basic latex. It's not very difficult.
