Hello, I am stuck on this question.

By applying kirchhoff's law to a parallel RLC circuit , we obtain the second order differential equation . ( L ) i + L di t ) = I at 2 R It Where i is the current through the circuit and I is the d. c. current source applied to the circuit . The capacitance ( = 10 x 10-9 F, inductance L = 50 x 10-3 H, resistance R = 1 x 10 32 and I = 50 * 10-3 A . Find an expression for i in terms of t
