Noun
the inverse function of the cosine; the angle that has a cosine equal to a given number
Source: WordNetAt that time he discovered alone series for sin x and cos x. Actually he found a series for cyclometric function arccos x and after that he just inverted this series and then guessed a principle for coefficients. Source: Internet
If θ measures elevation from the reference plane instead of inclination from the zenith the arccos above becomes an arcsin, and the cos θ and sin θ below become switched. Source: Internet

Angle main Positive and negative angles on the oriented plane The (non-reflex) angle θ ( 0° ≤ θ ≤ 180° ) between vectors x and y is then given by : where arccos is the arccosine function. Source: Internet
The principal inverses are usually defined as: : The notations sin −1 and cos −1 are often used for arcsin and arccos, etc. When this notation is used, the inverse functions could be confused with the multiplicative inverses of the functions. Source: Internet
