  Mathematics \Math`e*mat"ics\, n. [F. math['e]matiques, pl., L.
     mathematica, sing., Gr. ? (sc. ?) science. See {Mathematic},
     and {-ics}.]
     That science, or class of sciences, which treats of the exact
     relations existing between quantities or magnitudes, and of
     the methods by which, in accordance with these relations,


     quantities sought are deducible from other quantities known
     or supposed; the science of spatial and quantitative
     relations.
     [1913 Webster]
  
     Note: Mathematics embraces three departments, namely: 1.
           {Arithmetic}. 2. {Geometry}, including {Trigonometry}
           and {Conic Sections}. 3. {Analysis}, in which letters
           are used, including {Algebra}, {Analytical Geometry},
           and {Calculus}. Each of these divisions is divided into
           pure or abstract, which considers magnitude or quantity
           abstractly, without relation to matter; and mixed or
           applied, which treats of magnitude as subsisting in
           material bodies, and is consequently interwoven with
           physical considerations.
           [1913 Webster]

From The Collaborative International Dictionary of English v.0.48 [gcide]:

  Trigonometry \Trig`o*nom"e*try\, n.; pl. {-tries}. [Gr. ? a
     triangle + -metry: cf. F. trigonom['e]trie. See {Trigon}.]
     1. That branch of mathematics which treats of the relations
        of the sides and angles of triangles, which the methods of
        deducing from certain given parts other required parts,
        and also of the general relations which exist between the
        trigonometrical functions of arcs or angles.
        [1913 Webster]
  
     2. A treatise in this science.
        [1913 Webster]
  
     {Analytical trigonometry}, that branch of trigonometry which
        treats of the relations and properties of the
        trigonometrical functions.
  
     {Plane trigonometry}, and {Spherical trigonometry}, those
        branches of trigonometry in which its principles are
        applied to plane triangles and spherical triangles
        respectively.
        [1913 Webster]
