  In this article we propose some Maple procedures, for teaching purposes, to
study the basics of General Relativity (GR) and Cosmology. After presenting
some features of GRTensorII, a package specially built to deal with GR, we give
two examples of how one can use these procedures. In the first example we build
the Schwarzschild solution of Einstein equations, while in the second one we
study some simple cosmological models.
