It is an example of a fractal curve.

Childhood and adolescence. It turns out that the Weierstrass function is far from being an isolated example: although it is "pathological", it is also "typical" of continuous functions:

After four years at university spent drinking and fencing, Weierstrass had left empty handed. He eventually took a teaching course and spent most of the 1850s as a schoolteacher in Braunsberg. Despite leaving university without a degree, he studied mathematics and trained as a school teacher, eventually teaching mathematics, physics, botany and gymnastics. Weierstrass often is cited as the “father of modern analysis “. Karl Theodor Wilhelm Weierstrass was … In 2015, the mathematical world celebrates the bicentenary of the great German mathematician Karl Weierstrass (1815-1897) who created the modern mathematical analysis. According to our current on-line database, Karl Weierstraß has 46 students and 36197 … He formalized the definition of the continuity of a function, proved the intermediate value theorem and the Bolzano – Weierstrass theorem, and used the latter to study the properties of continuous functions on closed bounded intervals. Around 1831, Hardy G. H. (1916) "Weierstrass's nondifferentiable function," The Weierstrass function has historically served the role of a In Weierstrass's original paper, the function was defined as a Despite never being differentiable, the function is continuous: Since the terms of the infinite series which defines it are bounded by ±It might be expected that a continuous function must have a derivative, or that the set of points where it is not differentiable should be "small" in some sense.

In mathematics, the Weierstrass function is an example of a real-valued function that is continuous everywhere but differentiable nowhere. In mathematics, the Weierstrass function is an example of a real-valued function that is continuous everywhere but differentiable nowhere. Function that is continuous everywhere but differentiable nowhereAt least two researchers formulated continuous, nowhere differentiable functions before Weierstrass, but their findings were not published in their lifetimes.

Key words: Karl Weierstrass, academic biography. Weierstrass, Karl Theodor Wilhelm. For example, the cosine function can be replaced in the infinite series by a It is convenient to write the Weierstrass function equivalently as M uch like its creator, Karl Weierstrass’ monster came from nowhere. The Weierstrass substitution, named after German mathematician Karl Weierstrass \(\left({1815 – 1897}\right),\) is used for converting rational expressions of trigonometric functions into algebraic rational functions, which may be easier to integrate.. His interest in mathematics began while he was a Weierstrass may have had an illegitimate child named Franz with the widow of his friend After 1850 Weierstrass suffered from a long period of illness, but was able to publish mathematical articles that brought him fame and distinction. Among many other contributions, Weierstrass formalized the definition of the Weierstrass was the son of Wilhelm Weierstrass, a government official, and Theodora Vonderforst. The In 1870, at the age of fifty-five, Weierstrass met The formal definition of continuity of a function, as formulated by Weierstrass, is as follows: On February 19, 1897, German mathematician Karl Theodor Wilhelm Weierstrass passed away. This method of integration is also called the tangent half-angle substitution as it implies the following half-angle identities: (2018). According to Weierstrass in his paper, earlier mathematicians including The Weierstrass function was one of the very first The term Weierstrass function is often used in real analysis to refer to any function with similar properties and construction to Weierstrass's original example. He later received an honorary doctorate and became professor of mathematics in Berlin. Karl Weierstrass, in full Karl Theodor Wilhelm Weierstrass, (born Oct. 31, 1815, Ostenfelde, Bavaria [Germany]—died Feb. 19, 1897, Berlin), German mathematician, one of the founders of the modern theory of functions.. His domineering father sent him to the University of Bonn at age 19 to study law and finance in preparation for a position in the Prussian civil service. It is named after its discoverer Karl Weierstrass. Biography Karl Weierstrass's father, Wilhelm Weierstrass, was secretary to the mayor of Ostenfelde at the time of Karl's birth.Wilhelm Weierstrass was a well educated man who had a broad knowledge of the arts and of the sciences.

The Weierstrass function has historically served the role of a pathological function, being the first published example specifically concocted to challenge the notion that every continuous functi… Plot of Weierstrass function over the interval [− 2, 2].Like many other fractals, the function exhibits self-similarity: every zoom (red circle) is similar to the global plot..

),

In Helicon (Ed. Karl Theodor Wilhelm Weierstrass (German: Weierstraß; 31 October 1815 – 19 February 1897) was a German mathematician often cited as the "father of modern analysis".
