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.

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.
