An entry in the Pet Simulator series, Pet Simulator X sparked controversy among the Roblox community when the developers, BIG Games, integrated non-fungible tokens into the game, the first ever instance of such on the platform. [76] [non-primary source needed] [77] The game has been played over 5 billion times as of January 2023. [78]
In probability theory, the expected value (also called expectation, expectancy, expectation operator, mathematical expectation, mean, expectation value, or first moment) is a generalization of the weighted average. Informally, the expected value is the arithmetic mean of the possible values a random variable can take, weighted by the ...
Exponential functions with bases 2 and 1/2. The exponential function is a mathematical function denoted by () = or (where the argument x is written as an exponent).Unless otherwise specified, the term generally refers to the positive-valued function of a real variable, although it can be extended to the complex numbers or generalized to other mathematical objects like matrices or Lie algebras.
The exponential distribution is the special case of a Gamma distribution with shape parameter 1. If X ~ Exp (λ) and Xi ~ Exp (λ i) then: , closure under scaling by a positive factor. 1 + X ~ BenktanderWeibull (λ, 1), which reduces to a truncated exponential distribution. keX ~ Pareto ( k, λ). e−X ~ Beta (λ, 1).

Viète. de Moivre. Euler. Fourier. v. t. e. In trigonometry, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles.
In mathematics, Euler's identity[ note 1] (also known as Euler's equation) is the equality where. is pi, the ratio of the circumference of a circle to its diameter. Euler's identity is named after the Swiss mathematician Leonhard Euler. It is a special case of Euler's formula when evaluated for .
