Há 5 dias · Let's turn to Lambert's official definition of broad moral certainty, which is negative: broad moral certainty is just any non -geometrical certainty ( 1764/1990 II:408). All certainty is therefore either geometrical or broadly moral. Despite the name, geometrical certainty is not literally restricted to geometry.
Há 4 dias · The function W is called after the Swiss polymath Johann Heinrich Lambert (1728--1777) who found in 1758 series representation of the root for the equation y = q +ym. y = q + y m. Later his long time friend Leonhard Euler (1707--1783) solve more symmetric equation yα −yβ = ν(α − β)yα+β. y α − y β = ν ( α − β) y α ...
Há 6 dias · Johann Heinrich Lambert (1728--1777) was a Swiss polymath who made important contributions to the subjects of mathematics, physics (particularly optics), philosophy, astronomy and map projections. By implicit differentiation, one can show that all branches of W satisfy the differential equation
Há 4 dias · The function gd(x) = ∫x 0 dx coshx = 2tan − 1ex − π 2 is called the Gudermannian and connects trigonometric and hyperbolic functions. This function was named after Christoph Gudermann (1798-1852), but introduced by Johann Heinrich Lambert ( 1728 − 1777 ), who was one of the first to introduce hyperbolic functions.
Há 2 dias · Swiss scientist Johann Heinrich Lambert in 1768 proved that π is irrational, meaning it is not equal to the quotient of any two integers. Lambert's proof exploited a continued-fraction representation of the tangent function. French mathematician Adrien-Marie Legendre proved in 1794 that π 2 is also irrational.
Há 2 dias · Johann Heinrich Lambert conjectured that e and π were both transcendental numbers in his 1768 paper proving the number π is irrational, and proposed a tentative sketch proof that π is transcendental.
Há 5 dias · French scientist Pierre Bouguer and later Johann Heinrich Lambert, a Swiss scientist, investigated the absorption of light in transparent media and formulated Lambert’s law (Bouguer’s law or Bouguer-Lambert law) regarding the attenuation of a light beam in the media.
