Everytime I try to evaluate this integral, Mathematica 3.0 crashes and I
get a message saying MathKernel caused an invalid page fault . I have
tried this in Windows 95 and Windows NT environments but it always
crashes everytime I try to evaluate the integrate[ ] I hope some one
can help me try to resolve this problem
Thanks
