Sin(60°) = √3/2
Sine — the y-coordinate of the corresponding unit-circle point, or opposite/hypotenuse in a right triangle.
How to derive sin(60°)
In the same 30-60-90 triangle (sides 1, √3, 2), the side opposite 60° has length √3, so sin(60°) = √3/2.
Unit-circle context
The angle 60° corresponds to π/3 radians and sits Quadrant I on the unit circle.
