AlternateDefinition of Derivative

NotationThere are many ways to denote the derivative of a function y = f(x).  Besides f '(x), the most common notations are:

"y prime" Nice and brief, but does not namethe independent variable.

"dy dx" or "the derivative Names both variables andof y with respect to x" uses d for derivative.

"df dx" or "the derivative Emphasizes the function's name.of f with respect to x"

"d dx of f at x" or "the Emphasizes that differentiationderivative of f at x" is an operation performed on f.
