Hyperbolic Functions:



Hyperbolic sine
\operatorname{sh}x=\frac{e^x-e^{-x}}{2}

Hyperbolic cosine
\operatorname{ch}x=\frac{e^x+e^{-x}}{2}

Hyperbolic tangent
\operatorname{th}x=\frac{\operatorname{sh}x}{\operatorname{ch}x} = \frac {e^x - e^{-x}} {e^x + e^{-x}} = \frac{e^{2x} - 1} {e^{2x} + 1}

Hyperbolic cotangent
\operatorname{cth}x=\frac{1}{\operatorname{th}x}

Hyperbolic secant
\operatorname{sech}x=\frac{1}{\operatorname{ch}x}

Hyperbolic cosecant
\operatorname{csch}x=\frac{1}{\operatorname{sh}x}

Functions sh, ch, th, sech are continuous functions. Functions cth, csch are not defined for x=0.

Hyperbolic sine is increasing function passing through zero - \operatorname{sh}0=0.
Hyperbolic cosine is even function where \operatorname{ch}0=1 is the minimum.
