Laplace domain.

using the Laplace transform to solve a second-order circuit. The method requires that the circuit be converted from the time-domain to the s-domain and then solved for V(s). The voltage, v(t), of a sourceless, parallel, RLC circuit with initial conditions is found through the Laplace transform method. Then the solution, v(t), is graphed.
