Hyperbolic Cosine is one of the basic trigonometric hyperbolic function. In trigonometry, hyperbolic cosine can be expressed as cosh (x) = cos (ix). Cosh is a mathematical function with notation cosh(x). The hyperbolic functions take hyperbolic angle as real argument. Hyperbolic functions are the analogs of the ordinary trigonometric (circular) functions. Here is the online trigonometry Cosh Calculator which is used to calculate the Hyperbolic Cosine value.
