Curve of the sine function

null

Move the point P on the trigonometric circle. The point N has abscissa α and ordinate sin(α). The resulting curve is the graphical representation of the sine function on [0;2π].

Courbe de la fonction sinus

null

What happens to α when P makes more than one turn? How does the curve behave then? What if P turns in the nontrigonometric direction?
