Hi. I tried to solve some excersices but with this one I've got a little problem. I was asked to calculate the area of a circlesegment with radius R and midpointcorner 2*alpha. I have chosen the straigt side of the circlesegment to be parallel with the y axis.

I get these formulas in polarcoördinates.

oppp:=Doubleint(integrand(pool),r=R*cos(alpha)/cos(theta)..R,theta=-alpha..alpha);
alpha R
