The instantaneous value of current, i amp, at t seconds is given by:
Find the value of
(a) The amplitude.
(b) The period.
(c) The frequency.
(d) The initial phase angle (when t = 0), expressed in both radians and degrees.
(e) The value of i when t = 2.5 s.
(f) The time (in milliseconds) when the current first reaches its maximum value.
