A standard notation for the

derivative, created by

Gottfried Wilhelm von Leibniz(1646-1716) who, along with

Isaac Newton, was one of the founders of

calculus.

The Leibniz notation for the derivative is **dy/dx**. This is read aloud as "the derivative with respect to x". Leibniz notation is often used in fields of study such as physics and economics, more often than **Dx** notation.
