Laplace transforms
Posted:
Apr 24, 2007 5:31 PM


hi, i was wondering if someone could explain the procedure for evaluating a laplace transform such as L{(t^n)(e^(kt))} for n>=0.
Im not looking for you to give me a solution, just get me started. Im just not sure what to do with this type of Laplace transform. Do i use integration by parts?
i know L{t^n}= (n!/(s^(n+1)) for s>0 AND L{e^(kt)}=1/(sk) for s>k, but i dont know what to do with the combination of the 2.
Thanx :)
EDIT: SORRY, I just realized I posted this in the geometry section. I will repost, you can delete this one.
