What are the values of sin 30, sin 60, sin 45, and sin 90 in numericals?Explanation: For sin 120 degrees, the angle 120° lies between 90° and 180° (Second Quadrant ). Since sine function is positive in the second quadrant, thus sin 120° value = √3/2 or 0.8660254. . . Since the sine function is a periodic function, we can represent sin 120° as, sin 120 degrees = sin (120° + n × 360°), n ∈ Z.
