GUDERMANNIAN FUNCTION PDF

Gudermann function. A definition for the Gudermann function is: gdx = / x. 0 secht dt. The function is also called the Gudermannian function or the hyperbolic. The Gudermannian function, named after Christoph Gudermann ( – ), relates the circular and hyperbolic trigonometric functions. You already asked ten similar questions. Expand 1 cosh ⁡ y in powers of e y, integrate term by term, expand 1 1 + e 2 y in powers of e y.
