Noun

trigonometry (countable and uncountable, plural trigonometries)

1. (geometry, mathematical analysis) The branch of mathematics that deals with the relationships between the sides and angles of (in particular) right-angled triangles, as represented by the trigonometric functions, and with calculations based on said relationships.
   • 1892, Edward Albert Bowser, A Treatise on Plane and Spherical Trigonometry, D. C. Heath & Co., page 1,

     Trigonometry was originally the science which treated only of the sides and angles of plane and spherical triangles; but it has been recently extended so as to include the analytic treatment of all theorems involving the consideration of angular magnitudes.

   • 2013, Paul Abbott, Hugh Neill, Trigonometry: A Complete Introduction, Hachette, unnumbered page,

     In fact, the earliest practical uses of trigonometry were in the fields of astronomy and hence navigation.

   • 2016, Carl F. Lorenzo, Tom T. Hartley, The Fractional Trigonometry, Wiley, page 8,

     The properties of these new trigonometries and identities flowing from the definitions are then developed.

     The trigonometries derived from these generalizations will be jointly termed "The Fractional Trigonometry."
