Processing ends successfully The cos graph given below starts from 1 and falls till -1 and then starts rising again. Arccos (Inverse Cosine) The cos inverse function can be used to measure the angle of any right-angled triangle if the ratio of the adjacent side and hypotenuse is given. Inverse cosine is the inverse of the basic cosine function. In the cosine function, the value of angle θ is taken to give the ratio adjacent/hypotenuse. However, the inverse cosine function takes the ratio adjacent/hypotenuse and gives angle θ . cos -1 (adjacent/hypotenuse) = θ.
