Use the polar coordinate substitution x = r cos and y = r sin in

Question:

Use the polar coordinate substitution x = r cos θ and y = r sin θ in Equation (15.6) to show that a doubling of ycauses a doubling of r for every fixed θ.  Show that if yincreases, then y = f (x) shifts upward with an increasing slope.
