A voltage is given by v(t) = 10sin(100πt+100◦) V. a) Use a cosine function to express v(t). b) Find the angular frequency, the frequency in hertz, the phase angle, the period, and the rms value. c) Find the power that this voltage delivers to a 75-ohm resistance. d) Find the ﬁrst value of time after t=0 that v(t) reaches its peak value. e) Sketch v(t) to scale versus time.
