I'm trying to find the inverse laplace transform from the following equation:
(5 * s * e^(-2*s))/(s^2 + 9).inverse_laplace(s,t),
although sage responds with:
ilt((5 * s * e^(-2*s))/(s^2 + 9)).
How do I find the inverse laplace transform from the equation above?

var('t',domain='positive')
laplace(heaviside(t),t,s)
returns an unevaluated function object in stead of returning `1/s`. Other functions such as `sin(t)` and `dirac_delta(t)` seem to give the correct results. Is this just a blind spot in laplace, or do I need to refine my domains on `s` or `t`?
If this transform just isn't implemented, is there an easy way for me to patch it locally?G BWed, 20 Apr 2016 01:14:14 +0200https://ask.sagemath.org/question/33152/
