  1. Section 8.5 Simple Harmonic Motion; Damped Motion; Combining Waves

  2. Frequency

  3. Suppose that an object attached to a coiled spring is pulled down a distance of 5 inches from its rest position and then released. If the time for one oscillation is 3 seconds, write an equation that relates the displacement d of the object from its rest position after time t (in seconds). Assume no friction.

  4. d = 25 cos (4t)

  5. . The x-intercepts of the graph of d occur when cos t = 0.

  6. Select several values of x and compute f1(x), f2(x) and f(x) = f1(x) + f2(x).
