Elements of Plane and Spherical Trigonometry: With Their Applications to Heights and Distances, Projections of the Sphere, Dialling, Astronomy, the ... and Geodesic Operations
Excerpt from Elements of Plane and Spherical Trigonometry
What, however, has been so successfully effected in other departments of mathematics has not yet been attempted with re d to Trigonometry. We have some excellent war on this subject, whose value it would ill become me to depreciate. But such of them us go extensively into the business of Trigonometry and its applications are too large and expensive for general circulation; while others, being confined almost en tirely to the elements, exclusive of the applications, must of necessity be restricted, both in point of circu lation and utility. There is one treatise, that of Emerson, which is a most copious store-house of curious and ele gant but they are so obscured by a defective notation, that the perusal of greater part of the book must, to a mathematical student, he as perplexing as the solution of a perpetual string of enigmss. It has been my aim to steer into a middle course, between that in which is resented a mere common place book of principles a theorems, and that which.

About the author
Olinthus Gregory
211 booksOlinthus Gilbert Gregory (29 January 1774 – 2 February 1841) was an English mathematician, author and editor.
He was born on 29 January 1774 at Yaxley in Huntingdonshire. Having been educated by Richard Weston, a Leicester botanist, in 1793 he published a treatise, Lessons Astronomical and Philosophical. Having settled at Cambridge in 1796, Gregory first acted as sub-editor on the Cambridge Intelligencer, and then opened a booksellers shop. In 1802 he obtained an appointment as mathematical master at the Royal Military Academy, Woolwich through the influence of Charles Hutton, to whose notice he had been brought by a manuscript on the Use of the Sliding Rule; and when Hutton resigned in 1807 Gregory succeeded him in the professorship. Failing health obliged him to retire in 1838, and he died at Woolwich on 2 February 1841.
