Evaluate cos(240) Step 1. Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because cosine is negative in the third quadrant. Step 2. The exact value of is . Step 3. The result can be shown in multiple forms. Exact Form:
Trig functions of special angles.
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.
