  skos:definition """En géométrie, le sinus d'un angle dans un triangle rectangle est le rapport entre la longueur du côté opposé à cet angle et la longueur de l'hypoténuse. La notion s'étend aussi à tout angle géométrique (compris entre 0 et 180°). Dans cette acception, le sinus est un nombre compris entre 0 et 1. Si l'on introduit une notion d'orientation, les angles peuvent prendre n'importe quelle valeur positive ou négative, et le sinus est un nombre compris entre −1 et +1. Le sinus d'un angle α est noté sin(α) ou simplement sin α.

The sine and cosine of an acute angle are defined in the context of a right triangle: for the specified angle, its sine is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse), and the cosine is the ratio of the length of the adjacent leg to that of the hypotenuse.
