Find the indicated area by double integration in polar coordinates: The area inside both the circles r = 1 and r = 2 sin u© BrainMass Inc. brainmass.com March 4, 2021, 5:53 pm ad1c9bdddf
I use theta instead of u. We know that the jacobian here is r.
r changes between 1 and 2sin(theta). To find ...
A double integral is solved. The polar coordinates are analyzed for circles.
