Answer 1

Maybe you can take a look on "sage". Sage is an opensource computer algebra system and you can nearly verything eg. Graphtheorie and Plotting like a boss. http://www.sagemath.org/

Answer 2

You can start by trying SymPy for intersection (specifically) here.

There is more to SymPy; it will fit most of the things you might want to do! Read the docs for all of its capabilities.
