Hi group, I've had an integral (a laplace-transformation) which mathematica doesn't know. Now i have an analytic expression for the integral. Is there a possibility to add the new integral to mathematica (for example in any kind of library)? My problem is, that this integral is only a part of a longer formula for which i need the transformation... Thanks!
