Solve the problem.The power dissipated in an electric circuit is given by the expression 
where R is the resistance of the circuit and I is the current through the circuit. For a sinusoidal alternating current, the current might be represented by the relation 
where A is the amplitude, f is the frequency, and t is time. Write an expression for P involving the sine function, and use a fundamental identity to write P in terms of the cosine function.
A. P = RA sin2(2?f t) ; P = RA - cos2(2?f t) B. P = RA2 sin2(2?f t) ; P = - RA2 cos2(2?f t) C. P = RA2 sin2(2?f t) ; P = RA2 - RA2 cos2(2?f t) D. P = RA sin2(2?f t) ; P = RA - RA cos2(2?f t)
