So now we can write the Laplace Transform of a pair of convolved functions as \[ \mathcal{L}\{ f(t) \ast g(t) \} = F(s)G(s)\] where \[\displaystyle{ f(t) \ast g(t) = \int_0^t{ f(t-x)g(x)~dx } }\] Now, we have to be careful here, \(f(t) \ast g(t)\) is NOT \(f(t)\) TIMES \(g(t)\) and the \(\ast\) notation does NOT mean composite either.

Laplace Transform of a convolution. Example Use convolutions to find the inverse Laplace Transform of F(s) = 3 s3(s2 − 3). Solution: We express F as a product of two Laplace Transforms, F(s) = 3 1 s3 1 (s2 − 3) = 3 2 1 √ 3 2 s3 √ 3 s2 − 3 Recalling that L[tn] = n! sn+1 and L[sinh(at)] = a s2 − a2, F(s) = √ 3 2 L[t2] L sinh(√ 3 t) = √ 3 2 L t2 ∗ sin(√ 3 t).

The Inverse Laplace Transform of a Product 1. Solving initial value problems ay00 +by0 +cy=f with Laplace transforms leads to a transform Y =F·R(s)+···. 2. If the Laplace transform F of f is not easily computed or if the inverse transform of the product is hard, it would be nice to have a direct formula for the inverse transform of a product.
