==Definition==

The '''hyperbolic cosine function''' denoted <math>\cosh</math>, is defined as follows:

<math>\cosh x = \frac{e^x + e^{-x}}{2}</math>

Here, <math>e^x</math> denotes the [[defining ingredient::exponential function]].

More abstractly, <math>\cosh</math> is the [[defining ingredient::even part]] of the exponential function.
