An alternating current is described by the function i(t) = – 13 sin(450t + 40°) milliamperes, where t is the time measured in seconds. Paying close attention to the units and rounding to the nearest hundredth, determine each of the following values. (a) Maximum current in milliamperes: (b) Period in milliseconds: (c) Phase shift in milliseconds
