Trigonometric problem

  1. Apr 23, 2009 #1
    Can anyone please give me some idea for this problem?
    The instantaneous power, p, in an electric circuit is given by p = iv,
    where v is the voltage and i is the current.
    Calculate the maximum value of power in the circuit if v=0.02 sin(100 pi t)volts and i=0.6 sin(100pi t+ pi/4 ) amp
    Calculate the first time that the power reaches a maximum value.
    [/I]

    How do you determine the maximum of a function in general?
