Signification de "del" dans le dictionnaire anglais

Del, ou Nabla, est un opérateur utilisé en mathématiques, en particulier, en calcul vectoriel, en tant qu'opérateur différentiel vectoriel, généralement représenté par le symbole nabla ∇. Lorsqu'elle est appliquée à une fonction définie sur un domaine à une seule dimension, elle désigne sa dérivée standard telle que définie dans le calcul. Lorsqu'il est appliqué à un champ, del peut désigner le dégradé d'un champ scalaire, la divergence d'un champ vectoriel ou la courbure d'un champ vectoriel, selon la manière dont il est appliqué. À proprement parler, del n'est pas un opérateur spécifique, mais plutôt une notation mathématique pratique pour ces trois opérateurs, ce qui rend les équations plus faciles à écrire et à se rappeler. Le del symbol peut être interprété comme un vecteur d'opérateurs de dérivées partielles, et ses trois significations possibles - gradient, divergence et curl - peuvent être formellement considérés comme le produit des scalaires, des produits de points et des produits croisés, respectivement, de la " Opérateur "avec le champ. Ces produits formels ne se déplacent pas nécessairement avec d'autres opérateurs ou produits. Del, or Nabla, is an operator used in mathematics, in particular, in vector calculus, as a vector differential operator, usually represented by the nabla symbol ∇. When applied to a function defined on a one-dimensional domain, it denotes its standard derivative as defined in calculus. When applied to a field, del may denote the gradient of a scalar field, the divergence of a vector field, or the curl of a vector field, depending on the way it is applied. Strictly speaking, del is not a specific operator, but rather a convenient mathematical notation for those three operators, that makes many equations easier to write and remember. The del symbol can be interpreted as a vector of partial derivative operators, and its three possible meanings—gradient, divergence, and curl—can be formally viewed as the product of scalars, dot product, and cross product, respectively, of the del "operator" with the field. These formal products do not necessarily commute with other operators or products.

Juan Antonio Bayona

I went to a festival pretending to work as a journalist to get free tickets and interview people I really admired. I remember one of these people was Guillermo del Toro.

Pepe Eliaschev

'Tiempos del Mundo' is insignificant as far as the newspaper market is concerned here in Buenos Aires.

Doug Jones

People who know your work and know your personality, they know your strengths and weaknesses. A director like Guillermo del Toro, he knows more about me than I do. I trust him when he tells me what part I'm going to be playing in something, because he's envisioned that that can only be done by me. He knows it.

Lionel Messi

The truth is that I don't have a favourite goal. I remember important goals more than I do favourite goals, like goals in the Champions League where I had the opportunity to have scored in both finals I have played in. Finals in the World Cup or Copa del Rey are the ones that have stayed with me for longer or that I remember more.

Molly Quinn

The Coen Brothers, Peter Jackson, and Guillermo del Toro have really made something of themselves and impacted people. I'd love to work with them sometime, too.
