Problem 9.3 - Complete Response of an RC Circuit With SIN Function Input
*
* The circuit for this problem is from textbook Example 9.10.
* Use sinusoidal (SIN) source as given in the problem statement.
* Remember to convert SIN to cosine function by using a 90 degree
* angle.
*
* Use PROBE to display the response waveform for the circuit. Add the
* expression for the steady-state response to the graph. Note that the
* transient response contributes only 1.7 volts at t=0 and dies out
* in approximately 1/2 cycle of the steady-state sinusoidal waveform.
* NOTE: When adding the steady-state part of the expression given
* below, remember to convert the 8.13 degrees to radians for the
* initial phase angle of the cosine function.
*
* The UIC option is necessary to get the correct response, because
* the cosine waveform does not have zero value at t=0.
* The complete response is v(t)=1.7exp(-4t) + 9cos(3t+8.13ø).
