Problem 9.5 - Complete Response of RL Circuit with SIN Function Input
*
* A sinusoidal source is switched into a circuit at t=0. The source
* voltage has the equation vs(t) = 170cos(377t + 75ø).
*
* Use PROBE to display the waveform of the circuit response. Add the
* expression for the steady-state voltage across the resistance R1,
* v2p(t) = 44cos(377t).
*
* The .TRAN analysis interval is to be 75 milliseconds (approximately
* 4.5 full cycles of the output waveform). The UIC statement must be
* included, since the cosine forcing function is not zero at t=0.
*
* ===> After the first program run, edit your program to remove the UIC
* statement. Use PROBE to graph the complete response of the circuit
* and the expression for the steady-state response. Can you explain
* the result observed on the waveform graph in this case?
