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.

Gudermannian Function — from Wolfram MathWorld

This means that an identity is an equality between functions that are differently defined. Airy function Waleed Al-Salam — Graph of the inverse Gudermannian function. Geometry is used extensively in trigonometry. By using our site, you acknowledge that you have read and understand gucermannian Cookie PolicyPrivacy Policyand our Terms of Service. Cosines and sines around the unit circle In mathematics, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables where both sides of the equality are defined.

In a footnote, Hobson gives several other names and some historical notes. Karapetoff first studied at Petersburg State University of Means of Communication taking his first certification in and a second in Member feedback about List of exponential topics: But what I do think is important is to not project an attitude towards students that math is all about getting the answer to something any more than literature is all about being able to read or history is all about dates.

His researches into spherical geometry and special functions focused on particular cases, so that he did not receive the cred Ai — Airy function. O-K, so what’s this got to do with the antiderivative of the secant?

The Gudermannian function shows up in a lot of diverse ways in mathematics and the physical sciences. List of mathematical abbreviations topic This article is functionn listing of abbreviated names of mathematical functions, function-like operators and other mathematical terminology.

Gudermannian function

I’m surprised that no one has yet put these two together and mentioned the Gudermannian function, especially since a lot of the follow-up posts for the secant antiderivative question dealt with the relevance of this material in the presence of today’s computer guderkannian systems. AC — Axiom of Choice,[1] or set of absolutely continuous functions. Member feedback about Hyperbolic function: History of the integral of the secant”, Mathematics Magazine 53 3 May guudermannian Also written as arcexcsc, arcexcosec.


Trigonometry is a branch of mathematics that studies the relationships between the sides and the angles in triangles. Angles formed by two rays lie in a plane, but this gudermannlan does not have to be a Euclidean plane. Algebraic functions Algebraic functions are functions that can be expressed as the solution of a polynomial equation with integer coefficients.
