👉 In mathematics, an arsinh function is a special function that represents the inverse of the hyperbolic sine function. Specifically, it is defined as: arcsinh(x) = ln((1 + x)/x) This means that the arsinh function returns the principal value of the hyperbolic sine function for any real number x greater than or equal to 1. It is often used in calculus and mathematical analysis to find the inverse of the hyperbolic functions. For example
