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)

I'm sorry for unclear description of the problem.
So once again, let R = C[x_1,\dots,x_n]$ be my basering.
I'm looking for the group G, wich leaves a finite set S of polynomes
invariant under its action. So the ideal I = S is invariant under the
G-action too. And because every constant polynome is
