## Different Notations

Before we start, we need to go over some different notations of the derivative:

1. Newton's notation: the derivative of f(x) is f '(x). It is especially good for demonstration purposes-- for example, on this site.

2. Leibniz's notation: the derivative of y=f(x) is dy/dx. Especially good for complicated manipulations-- for example, on the documents for download.

3. As an operator on a function-- the operator is marked by Dx.
