Derivative formulas and rules

Symbols used in the derivative formulas

f or f(x), and g or g(x) are both function of x.
k, l and n are three constants that belong to real numbers, in other words:

a is a constant that belongs to real positive number except 1. With math symbolic language:

f '(x) and g '(x) are, respectively, the derivative of f(x) and g(x).
k ' et x ' are, respectively, the derivative of a constant k and the variable x.
