Anexo:Constantes matemáticas

El contenido del presente anexo es un listado de constantes matemáticas.

Constantes y funciones matemáticas

La estructura de la tabla es la siguiente:

• Valor numérico de la constante y enlace a MathWorld o a OEIS Wiki.
• LaTeX: Fórmula o serie en el formato TeX.
• Fórmula: Para utilizar en Wolfram Alpha. Si en los cálculos, ∞ demora mucho tiempo, puede cambiarse por 20000, para obtener un resultado aproximado.
• OEIS: On-Line Encyclopedia of Integer Sequences.
• Fracción continua: En el formato simple [Parte entera; frac1, frac2, frac3, ...] , Plantilla:Overline si es periódica.
• Año: Del descubrimiento de la constante, o datos del autor.
• Formato web: Valor de la constante, en formato adecuado para los buscadores web.
• N.º: Tipo de Número
  • R - Racional
  • I - Irracional
  • A - Algebraico
  • T - Trascendental
  • C - Complejo

(La tabla se puede ordenar ascendente o descendente, por cualquiera de los campos, sin más que pulsar en los títulos del encabezado).
