The Math.cosh() static method returns the hyperbolic cosine of a number. That is,
𝙼𝚊𝚝𝚑.𝚌𝚘𝚜𝚑(𝚡)=cosh(x)=ex+e−x2mathtt{operatorname{Math.cosh}(x)} = cosh(x) = frac{mathrm{e}^x + mathrm{e}^{-x}}{2}
Because cosh() is a static method of Math, you always use it as Math.cosh(), rather than as a method of a Math object you created (Math is not a constructor).
Syntax example: Math.cosh(x)
