a). We can use the equation of a curve in polar coordinates to compute some areas bounded by such curves. The basic approach is the same as with any application of integration: find an approximation that approaches the true value. While doing some experiment, a class of mathematicians came up with a figure with a polar region R, as shown in the figure below. Find the area A of the polar region R. R b). Prove that lim [x"y"dxdy 0. %3B -- --- --
