Re: linear or non-linear

When a differential equation is referred to as linear or nonlinear, what is being referred to is the variable which appears with derivatives, in this case y.  So which ones are linear with respect to y?

Missbossyy, try them yourself, post your answers here, and we'll do what we can to help you if you're wrong.
