Cosine of angle calculator
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 arccos of 0.5 is 60°: arccos(0.5) = cos-1 (0.5) = 60° Arccos table WebFeb 1, 2024 · However, remember that they work only for angles between 0 ° 0\degree 0° and 90 ° 90\degree 90°.The above formulas rely on the fact that the angles to either side of the = = = sign are complementary, i.e., …
