Simple Harmonic Equations

When solving for Simple Harmonic Equations, you will use the equations:
and

distance = d
amplitude = A
time = t
period =
frequency =



Putting the equations to use:
Ex 1) A weight attached to a spring is pulled down 6 inches from it's resting position and then released. If it takes 4 seconds for one oscillation, write the equation that relates the distance d from its rest position after time (in seconds). Assume no friction.

A = 6
t = 4
period = =
frequency = =
