La idea de los logaritmos neperianos se publicó por primera vez en 1524, y Henry Briggs introdujo poco después los logaritmos comunes (de base 10), que eran más fáciles de usar. Las tablas de logaritmos se publicaron en muchas formas durante cuatro siglos. La idea de los logaritmos también se usó para construir la regla de cálculo, que ...
Discrete logarithm. In mathematics, for given real numbers a and b, the logarithm log b a is a number x such that bx = a. Analogously, in any group G, powers bk can be defined for all integers k, and the discrete logarithm log b a is an integer k such that bk = a. In number theory, the more commonly used term is index: we can write x = ind r a ...
Definition. The exponential of a matrix A is defined by =!. Given a matrix B, another matrix A is said to be a matrix logarithm of B if e A = B.. Because the exponential function is not bijective for complex numbers (e.g. = =), numbers can have multiple complex logarithms, and as a consequence of this, some matrices may have more than one logarithm, as explained below.

Logaritmo. In matematica, il logaritmo di un numero in una data base è l' esponente al quale la base deve essere elevata per ottenere il numero stesso. [1] In generale, se , allora è il logaritmo in base di , cioè, scritto in notazione matematica, Per esempio, il logaritmo in base di è poiché bisogna elevare alla terza potenza per ottenere ...
Le logarithme népérien, ou logarithme naturel, ou encore jusqu'au XXe siècle logarithme hyperbolique, transforme, comme les autres fonctions logarithmes, les produits en sommes. L'utilisation de telles fonctions permet de faciliter les calculs comprenant de nombreuses multiplications, divisions et élévations à des puissances rationnelles.
The decimal value of the natural logarithm of 2 (sequence A002162 in the OEIS ) is approximately. The logarithm of 2 in other bases is obtained with the formula. The common logarithm in particular is ( OEIS : A007524 ) The inverse of this number is the binary logarithm of 10: ( OEIS : A020862 ). By the Lindemann–Weierstrass theorem, the ...
