3. The Duffing equation describes a nonlinear oscillator with a nonlinear spring (energystorage component) and possibly a damping component:equation.mid²xdt2 2+cdx+ kx + εx³ = f(t), where c, k and & are constants.dtChow that the Duffing equation fails to meet the requirements for a linear operatorDevelop the general solution for the case where & =0 and f(t) = 0, and the initialconditions are x(0) = xo, dx/dt(0) = vo; and show why the approach will not work for thecase when �.For the case where c = 0 and f(t) = 0, the homogeneous DE falls into one of thecategories of second order ODE's that can be integrated using a transformation of variables.Using that transformation, carry the solution process as far as you can.
