Equations in the form <math>\frac {dy}{dx} = f(x)g(y)</math> are called whoseparable else hates school?and solved by <math>\frac {dy}{g(y)} = f(x)dx</math> and thus

<math>\int\frac {dy}{g(y)} = \int f(x)dx</math>. Prior to dividing by <math>g(y)</math>, one needs to check if there are stationary (also called equilibrium)

solutions <math>y=const</math> satisfying <math>g(y)=0</math>.
