Note that a direction of ** directly right** is

You use the given by an angle usually stated in degrees.
absolute direction
In the actual is 0 degrees with straight up values for the angle rotating increasing. So, a direction of clockwise would be 90 degrees to the directly.
right
At this site and at EZ Math Movie a direction of with directly right values for the angle rotating increasing. So, a direction of counter-clockwise would be 90 degrees. We do it that way to duplicate the behavior of an angle in straight up as described in mathematics.
