So far, we have just looked at a terminal point's distance to the right of the circle's center. However, we can also think about the point's vertical distance above the circle's center. Let's reconsider the angle measuring 1 radian. The applet below shows an angle with a measure of 1 radian whose initial ray is at the 3-o'clock position. There is a circle centered at the angle's vertex, and you can change the size of the circle using the slider...
