Hi Harsh,
Please have a look at our Development Workflow page[1] to get started. If
you have already gone through this, submit a pull request so that we can
review it and check it in. Start small and just push your preliminary ideas
first so that we can discuss and refine it.

Hi,
Sympy is directly using inverse Millen formula
Integral(exp(s*t)*F, (s, c - I*oo, c + I*oo))
to evaluate the inverse_laplace_transform function. But it is not working
well with some functions which can be easily evaluated by hand. For example
1. A NotImplementedError is raised when I tr
The solution to this is to call apart on the arguments. For instance
In [9]: apart(2/(s**2*(s**2 + 1)))
Out[9]:
2 2
- ── + ──
22
s + 1 s
In [10]: inverse_laplace_transform(-2/(s**2 + 1), s, t)
Out[10]: -2⋅sin(t)⋅Heaviside(t)
In [11]: inverse_laplace_transform(2/s**2,
I changed the inverse_laplace_transform function in
sympy.integrals.transforms to first break the given function in partial
fractions and calculate the inverse_laplace_transform as the sum of
inverse_laplace_transform of the partial fractions.

Sorry for a late reply.
Though equivocally breaking the function into partial fraction can
lead to bad results, applying partial fraction gives let us solve the
inverse_laplace_transforms which are not solvable now. So, I think as
of now we should go ahead with equivocally breaking the function in
The partial fraction decomposition can be done completely separately
in the integral transformation code. It doesn't have to happen in
integrate() at this point.
