Table des cosinus en degrés et radians The cosine is a trigonometric function of an angle, usually defined for acute angles within a right-angled triangle as the ratio of the length of the adjacent side to the hypotenuse. It is the complement to the sine. In the illustration below, cos (α) = b/c and cos (β) = a/c. pour sinus et cosinus en fonction de l’angle en degrés, de 0 à 90° Notez la valeur 1/2 pour 30° et 60°.
