Hace 2 días · The notations 1 and i for unit vectors in horizontal positive direction and vertical positive direction, respectively, were introduced by Leonhard Euler (1707--1783) who visualized complex numbers as points with rectangular coordinates, but did not give a satisfactory foundation for complex numbers theory.
Hace 2 días · The constant first appeared in a 1734 paper by the Swiss mathematician Leonhard Euler, titled De Progressionibus harmonicis observationes (Eneström Index 43). Euler used the notations C and O for the constant.
Hace 2 días · The Euler--Lagrange equation was first discovered in the middle of 1750s by Leonhard Euler (1707--1783) from Berlin ( Prussia) and the young Italian mathematician from Turin Giuseppe Lodovico Lagrangia (1736--1813) while they worked together on the tautochrone problem.
Hace 2 días · Alternatively, another form of the conjecture states that every even integer greater than two can be expressed as the sum of two primes. In a letter to Leonhard Euler in the year 1742, Christian Goldbach hazarded the guess as follows: Every integer which can be written as the sum of two primes can also be ….
