Cosine definition. Cosine is one of the most basic trigonometric functions. It may be defined based on a right triangle or unit circle, in an analogical way as the sine is defined: The cosine of an angle is the length of the adjacent side divided by the length of the hypotenuse. cos (α) = adjacent / hypotenuse = b / c.

2 Find the value of sin 105 + cos 105 YouTube
cos 105 degrees = - (√6-√2)/4. The cos of 105 degrees is - (√6-√2)/4, the same as cos of 105 degrees in radians. To obtain 105 degrees in radian multiply 105° by π / 180° = 7/12 π. Cos 105degrees = cos (7/12 × π). Our results of cos105° have been rounded to five decimal places. If you want cosine 105° with higher accuracy, then.

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.
