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.
