If you're thinking of symbolic manipulation of formulae then you're better off doing your derivations in languages like Maple or Mathematica. They're designed for symbolic computation.

EDIT: If Maple and Mathematica are too expensive for you then there are other options. Wikipedia has a fairly complete listing of computer algebra packages. http://en.wikipedia.org/wiki/Comparison_of_computer_algebra_systems
