WebIn a right-angled triangle, the cosine of an angle (θ) is the ratio of its adjacent side to the hypotenuse, that is, cos θ = (adjacent side) / (hypotenuse). Using the definition of inverse cosine, θ = cos -1 [ (adjacent side) / (hypotenuse) ]. Thus, the inverse cosine is used to find the unknown angles in a right-angled triangle. family feud registrationWebTrigonometric functions are functions related to an angle. There are six trigonometric functions: sine, cosine, tangent and their reciprocals cosecant, secant, and cotangent, respectively. Sine, cosine, and tangent are the most widely used trigonometric functions. Their reciprocals, though used, are less common in modern mathematics. family feud referencesWebCosine similarity. In data analysis, cosine similarity is a measure of similarity between two non-zero vectors defined in an inner product space.
