## Newton's Notation for Derivative

Newton's notation for the derivative of a function $y = \map f t$ with respect to the independent variable $t$ is:

- $\map {\dot f} t$

or:

- $\dot y$

which many consider to be less convenient than the Leibniz notation.

This notation is usually reserved for the case where the independent variable is time.
