WebCosh is the hyperbolic cosine function, which is the hyperbolic analogue of the Cos circular function used throughout trigonometry. It is defined for real numbers by letting be twice the area between the axis and a ray through the origin intersecting the unit hyperbola . Cosh [α] then represents the horizontal coordinate of the intersection point. Cosh may also be … WebFeb 27, 2024 · Definition of cosh. Cosh is a function in math called hyperbolic sine. We compute its value as follows. \small \cosh x = \frac {1} {2} (\mathrm {e}^x + \mathrm {e}^ {-x}) coshx = 21(ex + e−x) As you most surely remember, the standard cosine function has a twin called sine. Hyperbolic cosine has a twin as well! The formula for hyperbolic sine ...
