The Cephes library is available via anonymous FTP.  It has integration.
You might also examine the book: "Numerical Recipies in C".  It has a
companion disk.  Integration and differentiation routines are included.
Symbolic manipulation is harder.  I'd buy a package like Mathematica, 
Maple, Mathcad etc.
