To find the exact value of sin 60°, we can use the special right triangle with angles 30°-60°-90°.
In a 30°-60°-90° triangle, the side lengths are in the ratio1 : \sqrt{3} : 2
Therefore, in a triangle with a 60° angle, the side opposite the 60° angle is\sqrt{3}
Since sin is opposite over hypotenuse, we have:
\sin 60° = \frac{\text{opposite}}{\text{hypotenuse}} = \frac{\sqrt{3}}{2}
Therefore, the exact value of sin 60° is\boxed{\frac{\sqrt{3}}{2}}
