Consider the angle shown below that has a radian measure of 0. A circle with a radius of 2.5 cm is centered at the angle's vertex, and the terminal point is shown. sin (0) a. The terminal point's horizontal distance to the right of the center of the circle is therefore: = cos(0) = b. The terminal point's vertical distance above the center of the circle is Preview = 1.74 ch 2.5 cm Preview 1.79 cm times as large as the radius of the circle, and times as large as the radius of the circle, and therefore:
