What is the exact value of sin 60° as found on the unit circle?

The answer is

In order to find this, you need to draw a 30-60-90 triangle in the first quadrant with a 60 degree angle closest to the origin. Once you have that, you will note that, Sin is equal to the opposite side length over the hypotenuse. The opposite side is equal to the square root of 3 and the hypotenuse is equal to 2. So we just express it as such.

hope this .
