Wolfram released a home edition of Mathematica, if you ever wanted play with this sophisticated CAS now you can for US $295 http://www.wolfram.com/products/mathematicahomeedition/
I think you can also write math documents as complicated as you need with it, with math notation, symbols, plots, drawings; as notebooks, which can be exported in various file formats, including PDF.
