Homework Statement
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
Homework Equations
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?
