  1. Sep 4, 2009 #1

    I need laplace transform of the functions below:



    3pi/s^2 + 9pi^2

    Thanks in advance

    Do you mean you want the inverse Laplace transform? Typically, functions are written in terms of "t" and their Laplace transforms in terms of s. If so for the first one, use "partial fractions" to write it as A/x+ B/(x+ 30) and look up the inverse transforms in a table of transfroms.

    For the second and third, you should be able to look them up directly.

    Here's a pretty good table on line:
