*P5.4. A voltage is given by v(t) = 10 sin(1000x + 30°). First, use a cosine function to express v(t). Then, find the angular frequency, the fre quency in hertz, the phase angle, the period, and the rms value. Find the power that this voltage delivers to a 50-2 resistance. Find the first value of time after = 0 that v(t) reaches its peak value. Sketch v(t) to scale versus time.
