** Using WeBWorK **

Here is a file that implements prime notation for parserFunction objects. See the documentation in the file for details. The basics are that you load this file and then enable it in the context you want:

    loadMacros("parserFunctionPrime.pl");
    Context("Numeric");
    parser::FunctionPrime->Enable();

    parserFunction("f(x)" => "x sin(x^2) - 3x^2");
    parserFunction("g(x)" => "3 cos(1-x^3)");
    $fog_prime = Compute("f'(g(x))g'(x)");

Hope that does what you need.
