The Inverse Laplace Transform

www.math.unl.edu

3. Example: Suppose you want to find the inverse Laplace transform x(t) of X(s) = 1 (s +1)4 + s − 3 (s − 3)2 +6. Just use the shift property (paragraph 11 from the previous set of notes): x(t) = L−1 ˆ 1 (s +1)4 ˙ + L−1 ˆ s − 3 (s − 3)2 +6 ˙ = e−t t3 6 + e3t cos √ 6t. 4. Example: Let y(t) be the inverse Laplace transform of ...

These lecture notes arose from the course \Partial Di erential Equations" { Math 124A taught by the author in the Department of Mathematics at UCSB in the fall quarters of 2009 and 2010. The selection of topics and the order in which they are introduced is based on [Str]. Most of the problems appearing in this text are also borrowed from Strauss.

Laplace transform for both sides of the given equation. For particular functions we use tables of the Laplace transforms and obtain s(sY(s) y(0)) D(y)(0) = 1 s 1 s2 From this equation we solve Y(s) s3 y(0) + D(y)(0)s2 + s 1 s4 and invert it using the inverse Laplace transform and the same tables again and
