71Euler line — In geometry, the Euler line, named after Leonhard Euler, is a line determined from any triangle that is not equilateral; it passes through several important points determined from the triangle. In the image, the Euler line is shown in red. It… …
72Euler's identity — [ 300px|thumb|right|The exponential function e z can be defined as the limit of nowrap|(1 + z / N ) N , as N approaches infinity, and thus e iπ is the limit of nowrap|(1 + iπ/N ) N . In this animation N takes various increasing values from 1 to… …
73Euler characteristic — In mathematics, and more specifically in algebraic topology and polyhedral combinatorics, the Euler characteristic is a topological invariant, a number that describes one aspect of a topological space s shape or structure. It is commonly denoted… …
74Euler equations (fluid dynamics) — In fluid dynamics, the Euler equations govern inviscid flow. They correspond to the Navier Stokes equations with zero viscosity and heat conduction terms. They are usually written in the conservation form shown below to emphasize that they… …
75Euler's three-body problem — In physics and astronomy, Euler s three body problem is to solve for the motion of a particle that is acted upon by the gravitational field of two other point masses that are either fixed in space or move in circular coplanar orbits about their… …
76Euler, Leonhard — born April 15, 1707, Basel, Switz. died Sept. 18, 1783, St. Petersburg, Russia Swiss mathematician. In 1733 he succeeded Daniel Bernoulli (see Bernoulli family) at the St. Petersburg Academy of Sciences. There he developed the theory of… …
77Euler–Worpitzky–Chen polynomials — Introduction = The Euler Worpitzky Chen polynomials are closely related to the family of Euler Bernoulli polynomials and numbers. The coefficients of the polynomialsare integers, in contrast to the coefficients of the Euler and Bernoulli… …
78Euler D-Typen — Die Euler D.I und D.II waren Kampfeinsitzer der deutschen Fliegertruppe im Ersten Weltkrieg. Inhaltsverzeichnis 1 Entwicklung 2 Einsatz 3 Technische Daten[2] 4 Literatur 5 …
79Euler–Maclaurin formula — In mathematics, the Euler–Maclaurin formula provides a powerful connection between integrals (see calculus) and sums. It can be used to approximate integrals by finite sums, or conversely to evaluate finite sums and infinite series using… …
80Euler-Poincare-Charakteristik — Die Euler Charakteristik ist in der Topologie (einem Teilgebiet der Mathematik) eine Kennzahl für geschlossene Flächen. Flächen, die unter topologischen Gesichtspunkten als gleich angesehen werden, haben dieselbe Euler Charakteristik. Sie ist… …
