WebThe atanh () function in C++ returns the arc hyperbolic tangent (inverse hyperbolic tangent) of a number in radians. The atanh () function takes a single argument and returns the arc hyperbolic tangent of that value in radians. The function is defined in header file. [Mathematics] tanh -1 x = atanh (x) [In C++ Programming] WebNotes. Inverse tangent (or arc tangent) is a multivalued function and requires a branch cut on the complex plane. The branch cut is conventionally placed at the line segments (-∞i,-i) and (+i,+∞i) of the imaginary axis. The mathematical definition of the principal value of inverse tangent is atan z = -. 1.
