find the area of the region shared by the curves r=6cosx and r=6sinx
i know that if you graph those two functions you get two circles, both with radius 3, the first one has its center on the cartesian x-axis and the other has its center on the y axis.
i also know that if you draw a line through the center of where they meet the angle of that line is pi/4
what i don't know is which function to integrate and what would be the lower limit of integration.
i know that the formula is 1/2 integral from a to b of (g(x)^2 - f(x)^2)
making 6sinx the second function makes sense since that's the bottom part of the area that i want to find but you can't make the first function 6cosx and integrate from 0 to pi/4 because that would give you more than just where the two functions overlap
any help or ideas about how to solve this would be appreciated.
