Trig functions of special angles.
Trigonometry is a branch of mathematics concerned with relationships between angles and ratios of lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies.

Cos 240 Degrees Find Value of Cos 240 Degrees Cos 240°
Solution Compute the value of the given expression: Given: cos ( 240 °) = cos ( 270 ° - 30 °) using identity cos ( 270 ° - A) = - sin ( A) cos ( 270 ° - 30 °) = - sin ( 30 °) ⇒ cos ( 240 °) = - 1 2 Therefore, the value of the given expression is - 1 2. Hence, the exact value for cos ( 240 °) is - 1 2. Suggest Corrections 17 Related Videos

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.
