The current I, in amperes, flowing through an ac (alternating current) circuit at time t, in seconds, is given below. What is the period? What is the amplitude? What is the phase shift? Graph this function over two periods. I(t) = 120 sin 30rt - 3 t20 What is the period? (Simplify your answer. Type an exact answer, using n as needed. Use integers or fractions for any numbers in the expression.)
