Hi! Im having a little (a lot) of trouble with some inverse Laplace problems. If anyone can help, I would really appreciate it!!! 1. 10s/(s^2+256)^2 2. 6s+6/(s+14)(s^2+4) With 1. I have tried countless ways of rearranging etc. getting (s^2+16^2)^2 to try to work it out that way... Im thinking it should either fit with either sin(wt)-atcos(wt) OR sin(wt)+at cos (wt) but I cant get the a and w right! :( with 2. I know that it needs to be expanded using partial fractions (A+Bs+C) But I cant work out what the numerator is meant to me I think the deniminator is s+7, (s+7)^2, (s+7)^3, (s+7)^4 And that I can bring that out as a constant and have e^-7t before those terms, but once again, Help!! Thanks again!!
