A logarithm is the inverse function of exponentiation, and has the form logb x = y, where b is the base and x is the argument. Learn about the properties of logarithms, such as logarithmic identities, logarithmic scales, and logarithmic functions.
Learn about the standardized text file format used by web servers to generate server log files. See the syntax, example, and usage of the Common Log Format and its extensions.
In science and engineering, a log–log graph or log–log plot is a two-dimensional graph of numerical data that uses logarithmic scales on both the horizontal and vertical axes. Power functions – relationships of the form y = a x k {\displaystyle y=ax^{k}} – appear as straight lines in a log–log graph, with the exponent corresponding to ...
A common logarithm is the logarithm with base 10, also known as the decadic or decimal logarithm. It is indicated by log (x), log10(x), or lg (x) and has the property that the logarithm of numbers differing by a power of 10 have the same fractional part.
A log-normal distribution is a continuous probability distribution of a random variable whose logarithm is normally distributed. Learn about its properties, generation, parameters, applications, and related concepts.
The natural logarithm of a number is its logarithm to the base of the mathematical constant e, which is an irrational and transcendental number. The natural logarithm of x is generally written as ln x, loge x, or simply log x, and has various properties and applications in mathematics.
Learn about the properties and formulas of logarithms, such as the log laws, the change of base formula, and the trivial identities. See derivations, explanations, and examples of how to use logarithms for computational purposes.
In algebraic geometry and the theory of complex manifolds, a logarithmic differential form is a differential form with poles of a certain kind. The concept was introduced by Pierre Deligne . [ 1 ] In short, logarithmic differentials have the mildest possible singularities needed in order to give information about an open submanifold (the ...
