Question

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

Answer 1

unit circle is on the last page of the attached cheat sheet
find 60 then find the coordinates on the unit circle
first coordinate is cosine
second coordinate is sine

Answer 2

You require a special \(30^\circ\)-\(60^\circ\)-\(90^\circ\) Triangle:

You can see that \(sin(\theta)\) is opposite over hypotenuse which is:
\[\frac{\sqrt{3}}{2}\]
