COSH

The Excel COSH function returns the hyperbolic cosine of a number, which represents a hyperbolic angle. Given the input of 1, the function returns the value 1.543080635. The hyperbolic cosine function returns the horizontal component of the point on the right branch (x ≥ 1) of the unit hyperbola corresponding to the hyperbolic angle given as input. Together with the hyperbolic sine function, the functions parameterize the right branch of the unit hyperbola given by the equation x² - y² = 1. In plain language, this means that the two functions trace out the shape of the right branch of the unit hyperbola. Given a hyperbolic angle corresponding to a point on the hyperbola's curve, COSH returns the horizontal component of the point, while SINH returns the vertical component of the point. For
