WebThe arccosine function is the inverse function of cos(x). arccos(x) = cos-1 (x) For example, If the cosine of 60° is 0.5: cos(60°) = 0.5. Then the arccos of 0.5 is 60°: WebThe inverse cosine function, cos−1(a) cos − 1 ( a) is sometimes called the arccosine function, and notated arccos(a). arccos ( a). The inverse tangent function, tan−1(a) tan − …

WebFree math problem solver answers your trigonometry homework questions with step-by-step explanations. Web1. We now consider a composition of a trigonometric function and its inverse. For example, consider the two expressions sin(sin−1(√2 2)) sin ( sin − 1 ( 2 2)) and sin−1(sin(π)) sin − 1 ( sin ( π)). For the first one, we simplify as follows: sin(sin−1( √2 2))= sin(π 4) = √2 2 sin ( sin − 1 ( 2 2)) = sin ( π 4) = 2 2. For ... trailblazer abs light on
