Homework Statement
Problem is part of a double integral. but my boundries are:
1<=x^2 + y^2 <=9 so between 2 circles with r1=1 and r2=3
and x<=y and y<=sqrt(3x)
the first boundry is obviously pi/4 and/or 3pi/4
the answer is pi/3 and i have no idea how u get that.
u obviously have to switch to polar coordinates but x=rcost y=rsint have no resulted in anything.
