Exponential function
Exponential functions are functions of the form Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle f(s)=a^{s}} , 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,

The transcendental number e (2.7182818...) has the property that the derivative of the function ex is ex, since ln e = 1. This function is thus important in the solution of many types of differential equations. e is the canonical exponential function.
