Your objective is to obtain a Thevenin equivalent for the circuit shown in Fig. P7.46, given that i_s(t) = 3 cos 4 times 10^4 t A. To that end: (a) Transform the circuit to the phasor domain. (b) Apply the source-transformation technique to obtain the Thevenin equivalent circuit at terminals (a, b). (c) Transform the phasor-domain Thevenin circuit back to the time domain.
