thanks a lot. is there a way to solve it analytically using method of successive approximations? i'd imagine the solution could take a form of something like y(x) = A1*cos(x)+A2*x^2*cos(2x)+A3*x^3*cos(3x)+...

thanks, it actually applies to a specific physics problem thanks. it actually applies to a specific physics problem. i am trying to solve this for a non-linear spring-mass-damper system where the spring stiffness is not constant, but linearly proportional to displacement. thanks!

can someone help me solve the differential equation that takes the following form? y''+Ay'+By+Cy^2=f(x), y is function of x Thanks a lot!
