You can find the bounds like you do for integrals in Cartesian coordinates. Set the two expressions equal to each other.
theta = x
Find the area between the polar curves : r= 2-2cos(x) and r = -2.75cos(x)
i know the formula is
.5* Int( r1^2- r2^2, x, ?, ?)
I just dont know what the bounds are. since the graph seems to touch at only one point.
Help is appreciated.
