Using the right triangle and the Pythagorean Theorem, we can see that x2 + y2 = 1 Thus, the equation of the unit circle is x2 + y2 = 1

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  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
