A circle of radius 1 rolls around the circumference of a larger circle of radius 4. The epicycloid traced by a point on the circumference of the smaller circle is given by x = 5 cost – cos 5t and y = 5 sin t – sin 5t. Find the distance traveled by the point in one complete trip about the larger circle.
