Unit Circle Hand Trick Note: This trick is best used to help remember the first quadrant of the unit circle but it can be modified to recall the whole Unit

unity 3d We will use these coordinates in later sections to find trigonometric functions of special angles on the unit circle x 1 1 45o 2 2

united kingdom The equation for the unit circle is x2+y2=1 So if we know one of the two coordinates of a point on the unit circle, we can substitute that
