Inverse laplace transform.

The program ILAP performs inverse Laplace transform of rational fractions.
Example: for x/((x²+1)(x+2), type 'X/(X^2+1)' 'X+2' / ILAP to get the answer:

$$y(x)=\frac{1}{5}(2\cos(x)+\sin(x))+\frac{-2}{5}e^{-2x}$$

Remark 5   The name of the Laplace variable is the same name as the normal variable (and is contained in VX).
