What was Karl weierstrass known for?
Known as the father of modern analysis, Weierstrass devised tests for the convergence of series and contributed to the theory of periodic functions, functions of real variables, elliptic functions, Abelian functions, converging infinite products, and the calculus of variations.

When was the Weierstrass function first used?
1872
The Weierstrass function has historically served the role of a pathological function, being the first published example (1872) specifically concocted to challenge the notion that every continuous function is differentiable except on a set of isolated points.
Why is the Weierstrass function important?
Weierstrass’s work was very influential and formed a solid foundation for analysis for decades to come. He shocked the mathematical world by coming up with a function which is continuous everywhere but differentiable nowhere!
Who created the theory of functions?
The term “function” was introduced by Gottfried Wilhelm Leibniz (1646-1716) almost fifty years after the publication of Geometry. The idea of a function was further formalized by Leonhard Euler (pronounced “oiler” 1707-1783) who introduced the notation for a function, y = f(x).
Who is Karl Theodor?
Karl-Theodor, Duke in Bavaria (9 August 1839 – 30 November 1909), was a member of the House of Wittelsbach and a professional oculist. He was the favorite brother of the Empress Elisabeth of Austria, and father of Queen Elisabeth of the Belgians.
Why is the Weierstrass function not differentiable?
The higher-order terms create the smaller oscillations. With b carefully chosen as in the theorem, the graph becomes so jagged that there is no reasonable choice for a tangent line at any point; that is, the function is nowhere differentiable.
Who first used the function?
Gottfried Wilhelm Leibniz (1646 1716) in 1673 first used the word “function” in a sense close to its modern meaning. Johann Bernoulli (1667 1748) introduced the concept of function into new ar- eas.
What is the theory of functions?
Theory of functions of a complex variable, the historical name for complex analysis, the branch of mathematical analysis that investigates functions of complex numbers. Constructive function theory, the study of the connection between the smoothness of a function and its degree of approximation.
Who is Guttenberg in Germany?
Guttenberg is the chairman and a founder of Spitzberg Partners, an advisory and investment firm based in New York City. He returned to German politics during the 2017 federal election by making a speech which was widely described as a comeback.
Is Weierstrass function uniformly continuous?
Is it still uniformly continuous? Yes.
Does the Weierstrass function have an Antiderivative?
The antiderivative of the Weierstrass function is fairly smooth, i.e. not too many sharp changes in slope. This just means that the Weierstrass function doesn’t rapidly change values (except in a few places).
Who discovered the power function?
first given by Leonhard Euler. This is one of a number of characterizations of the exponential function; others involve series or differential equations.
What is theory of functions?
What is the contribution of Weierstrass?
Known as the father of modern analysis, Weierstrass devised tests for the convergence of series and contributed to the theory of periodic functions, functions of real variables, elliptic functions, Abelian functions, converging infinite products, and the calculus of variations.
What are Weierstrass elliptic functions?
In mathematics, the Weierstrass elliptic functions are elliptic functions that take a particularly simple form. They are named for Karl Weierstrass. This class of functions are also referred to as ℘-functions and they are usually denoted by the symbol ℘, a uniquely fancy script p. They play an important role in the theory of elliptic functions.
What is the Weierstrass p-function p(z)?
The Weierstrass p -function p(z) (p is Weierstrass’ notation) for given primitive periods 2ω1, 2ω3, Im(ω3 / ω1) > 0, is defined as the series p(z) = p(z; 2ω1, 2ω3) = = 1 z2 + + ∞ ∑
Who is Karl Weierstrass in math?
