    Trigonometric functions

    The sine function

    The function defined by :
    sin : R -> R : x -> sin(x)
    is called, the sine function.
    The images are bounded in [-1,1] and the period is 2.pi .
    We say that the range of the function is [-1,1].

    The cosine function

    The function defined by :
    cos : R -> R : x -> cos(x)
    is called, the cosine function.
    The images are bounded in [-1,1] and the period is 2.pi .
    The range of the function is [-1,1].

    The tangent function

    The function defined by :
    tan : R -> R : x -> tan(x)
    is called, the tangent function.
    Now, the period is pi and the images are not defined in x = (pi/2) + k.pi
    The range or image is R.

    The cotangent ...
