Laplace Transforms
Description
Sage can compute Laplace transforms. The Laplace transform of $t^2e^t - \sin t$ is computed as follows:
Sage Cell
Code
s, t = var('s, t')
f = t^2*exp(t) - sin(t)
f.laplace(t,s)

We can also compute the inverse Laplace transform of
(1)\begin{align} F(s) = -\frac{1}{s^2 + 1} + \frac{2}{(s - 1)^3}. \end{align}
Code
s = var("s")
t = var("t")
F = -1/(s^2 + 1) + 2/(s - 1)^3
F.inverse_laplace(s,t)
