That way, if one has tried to analytically evaluate it, theycan pull it out and try numerically evaluating it easily. In fact, it probably could be done automatically.sage: a=integrate(250*cos(pi*x/180)^1.8 + 170.35 , x, 0, 18) sage: a integrate(250*cos(pi*x/180)^1.8 + 170.35, x, 0, 18) sage: a.arguments() (250*cos(pi*x/180)^1.8 + 170.35, x, 0, 18)
In that case, it should be simple to feed the integral to scipy. One could write a simple wrapper to numerically integrate integrals which can't be done analytically. Cheers, Tim. --- Tim Lahey PhD Candidate, Systems Design Engineering University of Waterloo http://www.linkedin.com/in/timlahey
