Differential Coefficient:

Some sources refer to a derivative as a differential coefficient, and abbreviate it D.C.

Some sources call it a derived function.

Such a derivative is also known as an ordinary derivative.

This is to distinguish it from a partial derivative, which applies to functions of more than one independent variable.

In his initial investigations into differential calculus, Isaac Newton coined the term fluxion to mean derivative.
