Hello, Sage groups, I have a problem, please see the example below, I wonder anyone can help me solve this problem:
f = Piecewise([[(0,pi/2),-1],[(pi/2,pi),2]]) a=pi*integrate(f,x,0,pi) a.show() b=pi*integrate(sin(x),x,0,pi) b.show() integrate(f*sin(x),x,0,pi) ----------------------------------------------- The first two integrations are right, but for the last one, I got the following error message: Traceback (click to the left of this block for traceback) ...
