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.

Algebraic functions Algebraic functions are functions that can be expressed as the solution of a polynomial equation with integer coefficients. Christoph Gudermann 25 March — 25 September was a German mathematician noted for introducing the Gudermannian function and the concept of uniform convergence, and for being the teacher of Karl Weierstrass, who was greatly influenced by Gudermann’s course on elliptic functions in —, the first such course to be taught in any institute.
I may write more about my thoughts another time, but for now I’ll just say that some of the proponents of skipping all the calculations and just using a computer algebra system seem to me to be too concerned with “getting the answer to some specific problem” at the expense of how the problem and the techniques for solving it are related to other problems and other techniques. The Gudermannian functionnamed after Christoph Gudermann —relates the circular functions and hyperbolic functions without explicitly using complex numbers.

A modern, abstract point of view contrasts large function spaces, which are infinite-dimensional and within which most functions are ‘anonymous’, with special functions picked out by properties such as symmetry, or relationship to harmonic analysis and group representations. The logistic curve Plot of the error function A sigmoid function is a mathematical function having a characteristic “S”-shaped curve or sigmoid curve. This means that an identity is an equality between functions that are differently defined.

Member feedback about Gydermannian of mathematical functions: List of trigonometric identities topic 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.

Rhumb line topic Image of a loxodrome, or rhumb line, spiraling towards the North Pole In navigation, a rhumb line, rhumb, or loxodrome is an arc crossing all meridians of longitude at the same angle, that is, a path with constant bearing as measured relative to true or magnetic north.
In geography, latitude is a geographic coordinate that specifies the north—south position of a point on the Earth’s surface. This is a list of special function eponyms in mathematics, to cover the theory of special functions, the differential equations they satisfy, named differential operators of the theory but not intended to include every mathematical eponym.

Introduction The effect of following a rhumb line course on the surface of a globe was first discussed by the Portuguese mathematician Pedro Nunes inin his Treatise in Defense of the Marine Chart, with further mathematical development by Thomas Harriot in the s. Anyway, back to Don Katze’s question.
Lines of constant latitude, or parallels, run east—west as circles parallel to the equator.
