The inverse sine function, on the other hand, is antisymmetric, i.e., it satisfies sin-1(-x) = -sin-1(x). How do I calculate cos-1 of one half? To determine the inverse cosine of ½: Sketch a right-angled triangle. Recall that the cosine is equal to the ratio of the ...
Thearccosineof x is defined as the inverse cosine function of x when -1≤x≤1. When the cosine of y is equal to x: cosy=x Then the arccosine of x is equal to the inverse cosine function of x, which is equal to y: arccosx= cos-1x=y ...

Cos need to enable equal options.
Thus, the cosine of angle α in a righttriangleis equal to the adjacent side’s length divided by the hypotenuse. To find the ratio of cosine, simply enter the length of the adjacent and hypotenuse and simplify. For example, let’s calculate the cosine of angle α in a triangle with th...
