H.W. Find I, ly, R, and Ry
To find the integral of a function f(x,y) over a region R, the region is
divided into rectangles when we work with polar coordinates (r, 0), it is
natural to divide R into "polar rectangles".

Multiple Integral
Suppose that a function f(r, 0) is defined over a region R bounded by the
rays 0 = a and 0 = B and the continuous curves r = f.(0) and r =
f(0) as shown in the figure below:
8=TT/2
r= f(8
