I've been following the sage package, and recently wanted to see how it was doing with symbolic mathematics.
It seems that it's doing well: http://www.sagemath.org/doc/ref/module-sage.calculus.calculus.html It can integrate/differentiate and maintain the symbolic form: sage: f = sin(x)/cos(2*y) sage: f.derivative(y) 2*sin(x)*sin(2*y)/cos(2*y)^2 sage: g = f.integral(x); g -cos(x)/cos(2*y) I should be a bit more precise: it is not using Math Notation, but script notation. But none the less, it appears to do a good job. It also can output LaTeX expressions, not sure if it can input them however. -- Owen ============================================================ FRIAM Applied Complexity Group listserv Meets Fridays 9a-11:30 at cafe at St. John's College lectures, archives, unsubscribe, maps at http://www.friam.org
