Synopsis

Elements Of Trigonometry, Plane And Spherical: With The Principles Of Perspective, And Projection Of The Sphere by John Wright. Elements Of Trigonometry is a two-part mathematical treatise that surveys plane and spherical trigonometry and connects them to perspective and projection. Part I develops plane trigonometry with definitions, procedures for constructing tables of natural sines, tangents, and secants, logarithms, scales, and the use of mathematical instruments like the fector; it includes right- and oblique-triangle theory, and Napier's logarithms. Part II covers the Principles Of Perspective, detailing the optical basis of perspective, the projection of spheres, orthographic and stereographic projection, and the projection of solids. The spherical section uses Napier’s rules to solve spherical triangles and demonstrates how spherical results can be reduced to plane problems, with numerous examples and applications to maps, astronomy, and celestial projection.
