Hace 3 días · Euler's constant (sometimes called the Euler–Mascheroni constant) is a mathematical constant, usually denoted by the lowercase Greek letter gamma ( γ ), defined as the limiting difference between the harmonic series and the natural logarithm, denoted here by log : Here, ⌊·⌋ represents the floor function .
Hace 2 días · Their first son was Johann Albrecht Euler, whose godfather was Christian Goldbach. Three years after his wife's death in 1773, Euler married her half-sister, Salome Abigail Gsell (1723–1794). This marriage lasted until his death in 1783.
Hace 4 días · The relation to the Euler numbers and π. The Euler numbers are a sequence of integers intimately connected with the Bernoulli numbers. Comparing the asymptotic expansions of the Bernoulli and the Euler numbers shows that the Euler numbers E 2n are in magnitude approximately 2 / π (4 2n − 2 2n) times larger than the Bernoulli numbers B 2n ...
Hace 5 días · In 1768, Leonhard Euler (St. Petersburg, Russia) introduced a numerical method that is now called the Euler method or the tangent line method for solving numerically the initial value problem: \[ y' = f(x,y), \qquad y(x_0 ) = y_0 , \]

A linear system of differential equations. ty˙ =Ay, t y ˙ = A y, where y˙ =dy/dt y ˙ = d y / d t and A is a constant square matrix, is called an Euler system of equations or a Cauchy--Euler system of equation.
Hace 3 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.
