- amplitude (A)
- period (T)
- frequency (f)
- angular frequency (w)
- initial phase (f)
- maximum velocity (v(t)max) and
- maximum acceleration (a(t)max)

One minimum set of parameters to completely specify the motion is:

- amplitude (A)

angular frequency (w)

initial phase (f)

- x(t) = A cos (wt + f)

Once you have A, w and f, you can calculate anything.
