In Exercises sketch the appropriate curves. A calculator may be used.

If the upper end of a spring is not fixed and is being moved with a sinusoidal motion, the motion of the bob at the end of the spring is affected. Sketch the curve if the motion of the upper end of a spring is being moved by an external force and the bob moves according to the equation y = 4 sin 2t − 2 cos 2t.
