A Treatise of Trigonometry Plane and Spherical ...

<p><i>A Treatise of Trigonometry Plane and Spherical</i> by Samuel Heynes originally published in 1716 offers a comprehensive exploration of trigonometry and its applications. This historical text delves into both plane and spherical trigonometry providing readers with a robust understanding of the principles and methods of the era. Additionally the treatise includes a detailed examination of stereographic and orthographic projection of the sphere. </p><p>Illustrated with examples in the stereographic projection of right and oblique angled spherical triangles this work serves as a valuable resource for those interested in the historical development of mathematical techniques and their practical uses in fields such as astronomy and navigation. It stands as a testament to the mathematical rigor and ingenuity of the early 18th century.</p><p>This work has been selected by scholars as being culturally important and is part of the knowledge base of civilization as we know it.
