See the formula, calculator, examples, and special angles for arccosine.Except where explicitly stated otherwise, this article assumes sin bình + cos bình = 1 Sin bình = tg bình trên tg bình cộng 1. But make sure that you also understand the analysis behind this! 2.5403, the same as cos of 1 radian in degrees. 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. Related Symbolab blog posts. Learn the definition, formula, applications, and examples of the cosine function, and see the table of common cosine values. cos^ (-1) (1/sqrt2)=+-pi/4 As cos (+-pi/4)=1/sqrt2 and cos ratio is positive in first and fourth quadrant cos^ (-1) (1/sqrt2)=+-pi/4.
