A Circle in Polar Coordinates Consider the polar equation r = a cos 0 + b sin 0. (a) Express the equation in rectangular coordinates, and use this to show that the graph of the equation is a circle. What are the center and radius? (b) Use your answer to part (a) to graph the equation r= 2 sin 0 + 2 cos 0.
