Use the Pythagorean Identity to find the missing coordinate of this point on the unit circle:
At any point on the unit circle, the corresponding right triangle has a hypotenuse of
If you know the length of the vertical leg and the hypotenuse, how can you solve for the horizontal leg?
For any right triangle,
