## Homework Statement

(dy/dx) - cos

^{2}(x-y) = 0

## Homework Equations

## The Attempt at a Solution

I'm unsure where to start this. This isn't a liner equation of form (dy/dt) + p(t)y = g(t) ; and it's not separable nor an exact equation.

Is it illegal to make this (dy/dx) - cos

^{2}(x) + cos

^{2}y = 0 ?

Thanks for your time.
