Separation of Variables: Also presented as
Some sources present this as an equation in the form:
 * $\dfrac {\d y} {\d x} = \dfrac {\map g x} {\map h y}$

or:
 * $\map h y \dfrac {\d y} {\d x} = \map g x$

whose general solution is found by solving the integration:
 * $\ds \int \map h y \rd y = \int \map g x \rd x + C$

Other sources have:


 * $\map g x + \map h y \dfrac {\d y} {\d x} = 0$

whose general solution is found by solving the integration:
 * $\ds \int \map g x \rd x = -\int \map h y \rd y + C$
