  1. 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.

  2. Índice Bovespa. The Bovespa Index ( Portuguese: Índice Bovespa ), best known as Ibovespa is the benchmark index of about 86 stocks [1] traded on the B3 (Brasil Bolsa Balcão), accounting for the majority of trading and market capitalization in the Brazilian stock market. It is a weighted measurement index.

  3. Euler's formula, named after Leonhard Euler, is a mathematical formula in complex analysis that establishes the fundamental relationship between the trigonometric functions and the complex exponential function. Euler's formula states that, for any real number x, one has. where e is the base of the natural logarithm, i is the imaginary unit, and ...

  4. In probability theory and statistics, the exponential distribution or negative exponential distribution is the probability distribution of the distance between events in a Poisson point process, i.e., a process in which events occur continuously and independently at a constant average rate; the distance parameter could be any meaningful mono ...

  5. Hyperbolic functions occur in the calculations of angles and distances in hyperbolic geometry. They also occur in the solutions of many linear differential equations (such as the equation defining a catenary ), cubic equations, and Laplace's equation in Cartesian coordinates. Laplace's equations are important in many areas of physics, including ...

  6. Timeline of the top 5 countries. The five countries with the largest foreign exchange reserves almost all have reserves of at least 500 billion USD and higher and have maintained such an amount for at least a week. At present there are only six countries whose reserves are at such a figure; this includes China, Japan, Switzerland, India, Russia ...

  7. v. t. e. Global Peace Index ( GPI) is a report produced by the Institute for Economics & Peace (IEP) which measures the relative position of nations' and regions' peacefulness. [2] The GPI ranks 163 independent states and territories (collectively accounting for 99.7 per cent of the world's population) according to their levels of peacefulness.
