These fancy terms amount to the following: whether there is a term involving only time, t (shown on the right hand side in equations below). However, with increasing amplitude, the linear equation ceases to be valid. A non-linear differential equation is a differential equation that is not a linear equation in the unknown function and its derivatives (the linearity or non-linearity in the arguments of the function are not considered here). To see that this is in fact a differential equation we need to rewrite it a little. There are very few methods of solving nonlinear differential equations exactly; those that are known typically depend on the equation having particular symmetries. Helpful.
