Double integration of functions involving bessel functions and cosines/sines

  1. May 30, 2010 #1
    Dear All,
    Its my first post on this the physics forum.

    i have a question. Can we integrate double integrals involving bessel functions and sinusoids in maple. Also, the overlap of sine and cosine over the range of 0 to 2 * Pi must be exactly zero, but, in maple, it gives some value (of the order of -129). Is there any software, which can compute the exact double integral.
    The function i am trying to integrate numerically (please correct me if i am doing rigth by solving numerically):

    with 0<=phi>=2*Pi, and 0<=r>=125e-6.

    I tried with matlab's builtin functions, but the same problem of accuracy.

    Thanks in advance.
