Trigonometric value

Sin(360°) = 0

Sine — the y-coordinate of the corresponding unit-circle point, or opposite/hypotenuse in a right triangle.

How to derive sin(360°)

sin(360°)=0sin(360°) = 0

360° = 0° + 360°, one full revolution. The terminal side returns to the positive x-axis at (1, 0), so sin(360°) = 0, identical to sin(0°).

Unit-circle context

The angle 360° corresponds to 2π radians and sits on an axis on the unit circle.
