(Modeling) Voltage The voltage in common household current is expressed as V = 163 sin wt, where w is the angular speed (in radians per second) of the genera- tor at an electrical plant and t is time (in seconds). (a) Use an identity to express V in terms of cosine. (b) If w = 1207, what is the maximum voltage? Give the least positive value of t when the maximum voltage occurs.
