    It is sometimes used to mean "is defined as" or equals by definition.

    Gracias, amigos.

    does it differ in meaning from the triple-equals sign? [tex]\equiv[/tex]

    The triple-equals is usually used to denote that a function identically equals some constant number (or another function).
