What is sin 540°?
Answer
sin 540° =
0
Angle in radians: 540° = 3π. 540° = 360° + 180° — a full turn plus 180°: the point is on the x-axis, (−1, 0).
sin 540° = sin(540° − 360°) = sin 180°
P(cos 540°, sin 540°) = (−1, 0)
P(cos 540°, sin 540°) = (−1, 0)
The point lies on the x-axis, so its projection on the y-axis is 0: sin 540° = 0.
+1 turn: the drawing shows 180°.

FAQ
What is sin 540°?
sin 540° = 0
Why is sin 540° equal to 0?
540° ends at the same point as 180°, (−1, 0), and sine is its the y-coordinate, so sin 540° = 0.
Why does a calculator show −0.3466 for sin 540?
The calculator is in radian mode (RAD): it takes sin 540 as the sine of 540 radians, sin 540 rad ≈ −0.3466. Switch it to degrees (DEG): sin 540° = 0. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
