WebInverse cosine function. The arccosine of x is defined as the inverse cosine function of x when -1≤x≤1. When the cosine of y is equal to x: cos y = x. Then the arccosine of x is equal to the inverse cosine function of x, which is equal to y: arccos x = cos-1 x = y. Example. arccos 1 = cos-1 1 = 0 rad = 0° See: Arccos function.
