What have you done so far?
could anyone help me with this problem please?
A vibration is identified as having the sinusoidal wave form equation of: -
s=0.55sin(3t/10-0.12)
i) Using calculus determine, and prove, the (first) times at which the displacement is a MAXIMUM and also a MINIMUM to 6 dec places.
ii) Determine to 6 decimal places the value of the maximum and minimum displacements at these times.
