WebSolution: We have cos x = Adjacent Side/Hypotenuse and cos -1 x is an inverse function of cos x. We know that cos (π/6) = √3/2. Since π/6 ∈ [0, π], cos -1 (√3/2) = π/6 Answer: The value of x if cos -1 (√3/2) = x using the inverse cosine formula is π/6. Example 2: Evaluate cos (cos -1 5) and cos -1 (cos 5π/3) using inverse cosine properties. WebCosine calculator Arccos definition. The 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 … does any other country have a constitution
