arctansinhx

Arctansinhx, also known as the inverse hyperbolic tangent function, is a mathematical function that is the inverse of the hyperbolic tangent function. It is denoted as arctansinh(x) or atanh(x) and is defined for all real numbers x. The function is continuous and differentiable for all x in its domain.

The arctansinhx function is defined as the area under the curve of the hyperbolic tangent function from 0 to x. It can be expressed in terms of natural logarithms as follows:

arctansinh(x) = ln(x + sqrt(x^2 + 1))

The graph of the arctansinhx function is a curve that passes through the origin and approaches infinity as x approaches infinity. It is an odd function, meaning that arctansinh(-x) = -arctansinh(x) for all x in its domain.

The arctansinhx function has several applications in mathematics and physics. It is used in the solution of differential equations, in the calculation of certain integrals, and in the analysis of hyperbolic functions. It is also used in the study of hyperbolic geometry and in the theory of special relativity.
