'''Exponential functions''' are [[function]]s of the form <math>f(s)=a^{s}</math>, where ''a'' is a [[constant]] and ''s'' is a [[complex number]]. They are based on the mathematical [[operation]] of [[exponentiation]].
The derivative of an exponential function is,
<math>\frac{d}{dx}a^{x}=a^{x}\ln{a}</math>,
where <math>\ln{a}</math> is the [[natural logarithm]] for ''a''.
The [[transcendental number]] ''[[e]]'' (2.7182818...) has the property that the [[derivative]] of the function ''e''<sup>''x''</sup> is ''e''<sup>''x''</sup>. This function is thus important in the solution of many types of differential equations. ''e'' is the canonical exponential function.
