      quality; as, a survey of the stores of a ship; a survey of
      roads and bridges; a survey of buildings.

   3. The operation of finding the contour, dimensions,
      position, or other particulars of, as any part of the

      road or line through it.

   {Trigonometrical survey}, a survey of a portion of country by
      measuring a single base, and connecting it with various
      points in the tract surveyed by a series of triangles, the
      angles of which are carefully measured, the relative
      positions and distances of all parts being computed from
      these data.

   Syn: Review; retrospect; examination; prospect.

Trigonometric \Trig`o*no*met"ric\, Trigonometrical
\Trig`o*no*met"ric*al\, [Cf. F. trigonom['e]trique.]
   Of or pertaining to trigonometry; performed by the rules of
   trigonometry. --{Trig`o*no*met"ric*al*ly}, adv.

   {Trigonometrical lines}, lines which are employed in solving
      the different cases of plane and spherical trigonometry,
      as sines, tangents, secants, and the like. These lines, or
      the lengths of them, are trigonometrical functions of the
      arcs and angles to which they belong.
