WebAug 3, 2024 · Python returns 1.28~ radians. The reason is obvious when plotted visually, 1.28rad has the same cosine as 5rad, they're inverse angles. Every angle shares the same … WebThe answer is 120°. With inverse cosine, we select the angle on the top half of the unit circle. Thus cos -1 (–½) = 120° or cos -1 (–½) = 2π/3. In other words, the range of cos -1 is restricted to [0, 180°] or [0, π]. Note: arccos refers to "arc cosine", or the radian measure of the arc on a circle corresponding to a given value of ...
