Noun
-
Function of an angle expressed as a ratio of the length of the sides of right-angled triangle containing the angle (synset 113809172)
is a type of: function, map, mapping, mathematical function, single-valued function - (mathematics) a mathematical relation such that each element of a given set (the domain of the function) is associated with an element of another set (the range of the function)subtypes:
- sin, sine - ratio of the length of the side opposite the given angle to the length of the hypotenuse of a right-angled triangle
- arc sine, arcsin, arcsine, inverse sine - the inverse function of the sine; the angle that has a sine equal to a given number
- cos, cosine - ratio of the adjacent side to the hypotenuse of a right-angled triangle
- arc cosine, arccos, arccosine, inverse cosine - the inverse function of the cosine; the angle that has a cosine equal to a given number
- tan, tangent - ratio of the opposite to the adjacent side of a right-angled triangle
- arc tangent, arctan, arctangent, inverse tangent - the inverse function of the tangent; the angle that has a tangent equal to a given number
- cotan, cotangent - ratio of the adjacent to the opposite side of a right-angled triangle
- arc cotangent, arccotangent, inverse cotangent - the inverse function of the cotangent; the angle that has a cotangent equal to a given number
