How to solve for inverse cosine
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°: arccos (0.5) = cos -1 (0.5) = 60° Arccos table See also Cosine calculator Sine calculator Tangent calculator Arcsin calculator Arctan calculator Arccos function WebFree functions inverse calculator - find functions inverse step-by-step.
