A sinusoidal voltage source is zero at t = 0.2 microseconds and is "going positive" at that point, meaning that v(t') > 0 for t' = 0.21 microseconds. Furthermore, the voltage at t = 0 is -28 milliVolts and its next zero is at t = 8.2 microseconds. (a) What is the frequency of the voltage source in kHz? (b) Write the expression for v(t), as a cosine.
