Hyperbolic Cosine Calculator

Calculate the hyperbolic cosine of a number

The calculator will find the hyperbolic cosine of the given value.

The hyperbolic cosine $$$y=\cosh(x)$$$ is such a function that $$$y=\frac{e^x+e^{-x}}{2}$$$.

The domain of the hyperbolic cosine is $$$(-\infty,\infty)$$$, the range is $$$[1,\infty)$$$.

It is an even function.

Find $$$\cosh{\left(2 \right)}$$$.

$$$\cosh{\left(2 \right)}\approx 3.762195691083631$$$A
