Trigonometric formulas and identities
Trigonometric formulas and identities Since we have seen all the basic formulas, we are going to start listing them now and prepare for problem solving. In some cases, We’ll add some extra steps to show […]
Fonctions trigonométriques élémentaires
Fonctions trigonométriques élémentaires Après l’introduction des trois fonctions trigonométriques (Sinus, cosinus et tangente) d’un angle , nous allons introduire leurs inverses à ne pas confondre avec les fonctions inverses. Sécante: C’est l’inverse de la fonction […]
