Trigonometry is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical.

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.

For cos 195 degrees, the angle 195° lies between 180° and 270° (Third Quadrant ). Since cosine function is negative in the third quadrant, thus cos 195° value = - (√6+√2)/4 or -0.9659258. . . ⇒ cos 195° = cos 555° = cos 915°, and so on. Note: Since, cosine is an even function, the value of cos (-195°) = cos (195°).
