Well, I don't know algorithm of solving contour integrals in SAGE. This is my problem :( here is a part of function: integral ((105*r*log(r)/8 - 26.25*r^3 + 315*r/ 16)*(-16*(-9019809825*r^6/214953202 - 55910066901/ (671728756250*r^2))*cos(4*Q)/r^2 + ...) ds I'll be very grateful if you post a sage code of decision of this problem..
