To find the value of sin 330°, follow these steps:
Recognize the angle's reference angle: The angle 330° lies in the fourth quadrant. To find the reference angle, subtract 330° from 360°: Reference angle = 360° - 330° = 30°.
Determine the sine of the reference angle: The sine of 30° is a known value: sin 30° = 1/2.
Apply the sign based on the quadrant: In the fourth quadrant, sine values are negative. Therefore, sin 330° will be the negative of sin 30°: sin 330° = -sin 30° = -1/2.
Thus, the value of sin 330° is -1/2.
