WebExplanation: For sin 270 degrees, the angle 270° lies on the negative y-axis. Thus, sin 270° value = -1. Since the sine function is a periodic function, we can represent sin 270° as, sin 270 degrees = sin (270° + n × 360°), n ∈ Z. ⇒ sin 270° = sin 630° = sin 990°, and so on. Note: Since, sine is an odd function, the value of sin ...
