2 cosh(x) = (e^x + e^{−x}) | Home › Math & Conversions › Core Math & Algebra › Hyperbolic Function Explorer Hyperbolic Function Calculator & Explorer Evaluate hyperbolic functions like sinh, cosh, tanh and their inverses, see exponential definitions, and explore key identities with a quick reference table. All functions are evaluated for a real variable x . Hyperbolic functions take a dimensionless argument. Hyperbolic function calculator Choose a function, enter a value for x , and click Calculate . The tool evaluates the function numerically and compares equivalent definitions. Function sinh(x) = (e^x − e^{−x})
