Comment obtenir d’autres symboles mathématiques ?#
LaTeX propose un grand nombre de commandes de symboles mathématiques. Si beaucoup d’entre elles sont données dans un document très complet, cette page présente pour sa part les plus courantes.
Bien entendu, de nombreuses extensions proposent des symboles mathématiques supplémentaires (en plus de ceux offerts par mathtools ou amsmath) : par exemple, les extensions stmaryrd et yhmath.
Notez ici l’existence de Detexify, outil en ligne très pratique permettant de retrouver la commande d’un symbole en le dessinant.
