The polar form of is and polar form of is
My idea is to divide the working into two parts:
1) find the integral in 1st quadrant and multiply by 2 to include the region in 4th quadrant
2) find the integral in 2nd quadrant and multiply by 2 to include the region in 3rd quadrant
Integral in 1st quadrant:
Integral in 2nd quadrant:
Am I correct? Thanks
