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.
Find the Exact Value of Cosine of 105° (cos105°) Using Sum Identity for Cosine and the Unit
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.

How to Find the Value of Cos 105 Degrees? The value of cos 105 degrees can be calculated by constructing an angle of 105° with the x-axis, and then finding the coordinates of the corresponding point (-0.2588, 0.9659) on the unit circle. The value of cos 105° is equal to the x-coordinate (-0.2588). ∴ cos 105° = -0.2588.
