Hace 3 días · The Basel problem is a problem in mathematical analysis with relevance to number theory, concerning an infinite sum of inverse squares. It was first posed by Pietro Mengoli in 1650 and solved by Leonhard Euler in 1734, [1] and read on 5 December 1735 in The Saint Petersburg Academy of Sciences. [2]
Hace 1 día · This formula was discovered by William Chapple in 1746 [] and by Leonhard Euler in 1765 [2, 3].A bicentric polygon is a polygon with all vertices on a circle, called the circumcircle, and all sides tangent to another circle, called the incircle.
Hace 3 días · In 1764 Leonhard Euler employed Bessel functions of both zero and integral orders in an analysis of vibrations of a stretched membrane, an investigation which was further developed by Lord Rayleigh in 1878, where he demonstrated that Bessels functions are particular cases of Laplaces functions.
Hace 4 días · In Cartesian coordinates, a complex number is denoted by the ordered pair: z = (a, b), with Rz =Rez = a, Iz =Imz = b. z = ( a, b), with ℜ z = Re z = a, ℑ z = Im z = b. It was Leonhard Euler who suggested to use two unit vectors, 1 for the abscissa and i for the ordinate, allowing him to write.
Hace 5 días · This section presents a class of variable coefficient equations that admit closed form solutions---the Euler equations (also known as equidimensional equations).
Hace 5 días · Resumo. O artigo discute as teses apresentadas por Leonhard Euler, nas Reflexões sobre o espaço e o tempo. Após uma breve introdução ao debate sobre a natureza do espaço e do tempo, nos séculos XVII e XVIII, e como Euler nele se posiciona (seção 1), avançam-se duas hipóteses. A partir de uma aproximação com os textos de Isaac ...
Hace 1 día · Leonhard Euler's signature Leonhard Euler was one of the most prolific mathematicians in history, and also a prolific inventor of canonical notation. His contributions include his use of e to represent the base of natural logarithms .
