Explanation: For cos 240 degrees, the angle 240° lies between 180° and 270° (Third Quadrant ). Since cosine function is negative in the third quadrant, thus cos 240° value = - (1/2) or -0.5 Since the cosine function is a periodic function, we can represent cos 240° as, cos 240 degrees = cos (240° + n × 360°), n ∈ Z.

The Cosine function ( cos (x) ) The cosine is a trigonometric function of an angle, usually defined for acute angles within a right-angled triangle as the ratio of the length of the adjacent side to the hypotenuse. It is the complement to the sine. In the illustration below, cos (α) = b/c and cos (β) = a/c.
