Comment calculer un angle avec cos sin et tan ?
Alors n'oubliez pas SOH CAH TOA.
Sin = Opposé / Hypoténuse (S.O.H.) Cos = Adjacent / Hypoténuse (C.A.H.) Tan = Opposé / Adjacent (T.O.A.)Par exemple, le cosinus est le rapport entre le côté adjacent à l'angle par rapport à l'hypoténuse.
Le sinus est le rapport entre le côté opposé à l'angle par rapport à l'hypoténuse.
Quels sont les arcs de la trigonométrie ?
Les trois fonctions trigonométriques les plus utilisées sont le sinus (noté sin), le cosinus (cos) et la tangente (tan, tang ou tg).
