Circuit Second order

In summary, a 2nd order circuit is an electrical circuit with two energy storage elements and at least one second-order differential equation. To solve a 2nd order circuit problem, one must use differential equations, Kirchhoff's laws, and initial conditions. Common techniques for solving such problems include Laplace transforms, method of undetermined coefficients, and variation of parameters. Initial conditions refer to the voltage and current values at the beginning of the circuit's operation. There are no shortcuts or tricks for solving 2nd order circuit problems, it requires a thorough understanding of circuit analysis principles and mathematical techniques, and practice can make the process more efficient.

Im trying to solve this problem, but i rally do not know where to start and i am having a lot of trouble.

Vo" + 2Vo' + Vo = 10sin2t and Vo(0)=2, Vo'(0)=0

any help is much appreciated
