Solve the problem.A mass hangs from a spring which oscillates up and down. The position P of the mass at time t is given by P = 4 cos(4t)What is the amplitude? What is the period? Graph this function over two periods beginning at t = 0. 
What will be an ideal response?
amplitude = 4, period = 
| P = 4cos(4t) |
