Consider a rotating disk cam and a translating roller follower with zero offset. Which one of the following pitch curves, parameterized by t, lying in the interval 0 to 2π, is associated with the maximum translation of the follower during one full rotation of the cam rotating about the center at (x, y) = (0, 0)?

x(t) = ½ + cost t, y(t) = sin t

x(t) = ½ + cos t, y(t) = 2 sin t
