Find all values for which  10 A small toy attached to the end of a slinky (or spring) bobs up and down according to an equation of the form d = a cos(bt).  The motion of the toy starts at its highest position of 5 inches above its rest point, bounces down to its lowest position of 5 inches below its rest point, and then bounces back to its highest position in a total of 4 seconds.  Write an equation that represents this motion. Graph your equation from t = 0 seconds to t = 12 seconds.
