The COSH function returns the hyperbolic cosine of a number.

Syntax

=COSH(number)

Arguments

Argument Description
number Any real number for which you want to find the hyperbolic cosine

Examples

  A B C
1 Formula Result Notes
2 =COSH(4) 27.308233 Hyperbolic cosine of 4
3 =COSH(-2) 3.762195691 Hyperbolic cosine of -2
4 =COSH(EXP(1)) 7.6101251 Hyperbolic cosine of the base of the natural logarithm

The equation used to calculate the hyperbolic cosine is:   

    \[    COSH(z) = \frac{e^z + e^{-z}}2    \]
