Nonlinear Differential Equation Solving

Hello everyone.
I have a second order non-linear homogenous differential equation I want to solve.
Equation basicly is : A*y'' - B*y + C = D*cos(y)
How can i solve this? I am trying to acquire a solution in the form of y = ....
Note = y'' is second order derivative of y

The analytical solution probably does not exist.
syms y(t) A B C D
eqn = A*diff(y,t,2) - B*y + C == D*cos(y);
ySol(t) = dsolve(eqn)
Try ode45 instead if the parameters {A, B, C, D} are known. See some examples here:
