1. Problem 8.9
2. Problem 8.11a, d, f, g (sketch in complex plane showing both rectangular and polar coordinates)
3. Problem 8.12a, d, f, g (sketch in complex plane showing both rectangular and polar coordinates)
4. Given the sinusoid 4sin(5t - 0.2rad)
   • rewrite the sinusoid as a cosine only
   • determine the sinusoid's (as a cosine) amplitude, angular frequency, ordinary frequency, period, and phase angle
5. Given the sinusoids v(t) = 3cos(4t + 0.1rad) and i(t) = 2cos(4t - 0.6rad), determine in both radians and seconds how much v(t) leads or lags i(t).
