Problem on waveforms

The voltage v mV in a circuit is given by:

v = 20 sin (200 Πt - 0.7854)          

where t is the time in seconds

(a) State the amplitude, frequency, period and phase angle of v.
(b) Determine the initial voltage.
(c) Determine the value of t (> 0) when v first reaches its maximum value.
(d) Evaluate v at t = 4 x 10-3
(e) Sketch one cycle of this waveform.
