Then, when t = 0 you begin at the point ( r, 0). Then t increases until t = π / 2 and you arrive to the point ( 0, r), so you are going counterclockwise. If you want to go clockwise you can use ( r sin t, r ...

WebOrientation of three ordered points refers to the different ways in which the three points can be placed in a given space. The three given points can be placed in such a way that when we connect them, they either form a triangle or a straight line. The former case has two orientations i.e. clockwise and anti-clockwise.
