For cos 270 degrees, the angle 270° lies on the negative y-axis. Thus cos 270° value = 0. Since the cosine function is a periodic function, we can represent cos 270° as, cos 270 degrees = cos (270° + n × 360°), n ∈ Z. ⇒ cos 270° = cos 630° = cos 990°, and so on. Note: Since, cosine is an even function, the value of cos (-270.
