1. The problem statement, all variables and given/known data Integrate the double Integral: 6xdydx in polar coordinates The y goes from bottom limit of x(3)^(1/2) to the top limit of (1-x^2)^(1/2) the x goes from 0 to 1/2 2. Relevant equations 3. The attempt at a solution So I graphed it, and it looks like a semi circle on the positive y plane with a linear line going through it in the first domain. Changing this to polar coordinates I got Double Integral: 6r^2cosθdrdθ and for dr I evaluated it between 0 and 1 for dtheta, i'm having trouble figuring it out. It looked to me like it should go from pi/4 to pi/2, because the radius is one and x goes from 0 to 1/2 only. Any advice?
