Há 4 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 5 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 1 dia · 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 · In mathematics, the Lambert W function, also called the omega function or product logarithm, is a multivalued function, namely the branches of the converse relation of the function f(w) = we w, where w is any complex number and e w is the exponential function. The function is named after Johann Lambert, who

Há 2 dias · Powered by @Calculator Ultra. 双曲余弦（\ ( \cosh \)）是数学中一个重要的函数，与指数函数紧密相关。 与三角余弦不同，双曲余弦是使用指数函数来定义的。 历史背景. 双曲函数的概念是在 18 世纪提出的。 这些函数是普通三角函数或圆函数的类似物，但它们基于双曲线而不是圆。 Johann Heinrich Lambert 在 1760 年代创造了“双曲函数”一词，认识到了它们与双曲线的联系，这与三角函数与圆的联系方式类似。 计算公式. 双曲余弦定义如下： \ [ \cosh (x) = \frac {e^x + e^ {-x}} {2} \] 其中： \ (e\) 是自然对数的底数， \ (x\) 是计算双曲余弦的值。 计算范例.
