    Do you want numerical or symbolic integration?

    For a large list of computer algebra systems, see http://en.wikipedia.org/wiki/Comparison_of_computer_algebra_systems" [Broken]

    Here is an online numerical integrator: http://people.hofstra.edu/stefan_Waner/RealWorld/integral/integral.html" [Broken]

    OK. What I meant with symbolic integration was things like

    [tex]\int_{-1}^1\frac{1}{\sqrt{1+x^2}}dx=\log(\sqrt{2}+1})[/tex]

    instead of the answer .88137...
