1. Find the phasors for the following voltage sources and plot them as vectors on the complex plane:

1. v1(t) = 10 * cos (2*pi*f*t pi/3)
2. v2(t) = 12 * cos ( 2*pi*f*t + pi/4)

2. Consider two voltage sources with amplitudes A1 = 5 volts and A2 = 15 volts and phase angles of 30 and 60 degrees respectively. The frequency is 60 Hz for both of them.
   1. Construct phasor representations for these voltages and plot them as vectors on the complex plane.
   2. Perform the addition of these two phasors and plot the resulting vector on the same complex plane as in a).
