 Author Comment/Response igor_igel 04/27/12 8:29pm Hi, I have integrals similiar to this: Integrate[ Integrate[ x Piecewise[{{1, 1 + u - Floor[q] > x}, {0, 1 + u - Floor[q] <= x}}] f'''[x] , {x, 0, (1/q)}, Assumptions -> q > 0], {u, 0, (1/q)}, Assumptions -> q > 0] and my computer seems to get stuck and calculate infinitly long. I can solve these integrals with hand but it would be very usefull to solve with mathematica. If a simpler example is needed I can try to find one, just tell me. thanks in advance Igor Igel URL: ,
