Answer: Sin 270 degrees has a value of -1. In radians, sin 270 degrees is represented as sin (270°/180°), i.e., sin (3/2(π)) means sin (4.712388. . .).
Sin (-270 degrees): 1 Sin 270 degrees in radians: sin (3/2) = sin (4.7123889 . . .)
The angle 270° is already on the negatives y-axis with sin 270 degrees. Therefore, sin 270° values = -1
Because the output waveform is indeed a periodic function, one may write sin 270 degrees as sin(270° + n 360°), n Z. sin 270 degrees = sin 630 degrees = sin 990 degrees, and so on.
Its result of sin (-270°) Equals -sin (270°) since sine is indeed an odd function.
