Question in MY QUESTIONS
Equations which can be written in the form
\[\dfrac{\mathrm{d}y}{\mathrm{d}x} = f(x), \dfrac{\mathrm{d}y}{\mathrm{d}x} = f(y), \dfrac{\mathrm{d}y}{\mathrm{d}x} = f(x)f(y)\]
can all be solved by integration.
In each case it is possible to separate the $x$'s to one side of the equation and the $y$'s to the other
Solving such equations is therefore known as solution by separation of variables
