  • Quelles sont les formules de trigonométrie ?

    Sin = Opposé / Hypoténuse (S.O.H.) Cos = Adjacent / Hypoténuse (C.A.H.) Tan = Opposé / Adjacent (T.O.A.)

  • Comment calculer tan avec sin et cos ?

    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.
    Quant à la tangente, elle est le rapport entre la fonction sinus et cosinus.

  • C'est quoi sin cos Tan ?

    COSÉCANTE, subst. fém.
    TRIGONOMÉTRIE, rare. Inverse du sinus d'un angle, d'un arc, soit sécante du complément de l'angle, de l'arc.
