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

Starting at 0 degrees, rotate P in a counterclockwise direction. [br]How does the curve height compare to the height of the angle?[br]Why did the sine curve go below the x-axis in the negative direction?[br]What would happen if the angle P were to keep rotating, or go past 360 degrees?[br]How does the curve behave then?[br]What if P turns in a clockwise direction?
