Levi Leonard Conant (March 3, 1857, Littleton, Massachusetts – October 11, 1916, Worcester, Massachusetts) was an American mathematician specializing in trigonometry. William Arveson Dec. at 76 (1934-2011) William B. Arveson (22 November 1934 – 15 November 2011) wa...
In trigonometry, which he valued for its own beauty as well as practical applications, he developed spherical trig and was first to present the identity sin a+b = sin a · cos b + sin b · cos a Bháscara's achievements came centuries before similar discoveries in Europe. It is an...
Regiomontanus and Ptolemy are famous mathematicians of great historic importance whom I omit. Regiomontanus' work is important primarily because he lived shortly after Gutenberg's printing press invention; his actual creative achievements in spherical trigonometry were anticipated by Nasir al-Din al-Tusi...

He was the author of some studies on the aurora borealis, comets, and the effects of lightning, as well as of an important but unpublished work on flat and spherical trigonometry. He also wrote a commentary on the Principia of Isaac Newton (published in Geneva, 1739–42), for which he ...
