Free software is sooo cool! wxMaxima is a GUI frontend for Maxima, "a system for the manipulation of symbolic and numerical expressions, including differentiation, integration, Taylor series, Laplace transforms, ordinary differential equations, systems of linear equations, polynomials, and sets, lists, vectors, matrices, and tensors. Maxima yields high precision numeric results by using exact fractions, arbitrary precision integers, and arbitrarily precision floating point numbers. Maxima can plot functions and data in two and three dimensions."

At least it beats me at computing improper integrals, not hard BTW
Here is a tutorial...
