WebWhat is inverse cosine? The inverse cosine, also called the arc cosine and denoted cos-1 (x) or also arccos(x), is the inverse cosine function. This means that the inverse cosine reverses the effects of the cosine function. For example, the cosine of 60° is equal to 0.5. This means that the inverse cosine of 0.5 is equal to 60°.
