This work is of great historical importance as the first trigonometrical tables ever issued. Unfortunately, the work was unfinished at his death in 1574, but the publication of Rheticus's work was accomplished by his pupil Valentin Otho in 1596. These trigonometrical tables (as corrected by Bartholomaeus Pitiscus in 1613) were still in use in the early twentieth century.The mathematician and astronomer Georg Rheticus was the only pupil of Nicolaus Copernicus, whose De revolutionibus he helped publish. His major work was on the study of triangles, culminating in this comprehensive set of tables to be used in angular astronomical measurements; it also includes the first use of the word "cosecant". It was completed and published after his death by Valentin Otho (c.1545-1603). The tables were accurate enough to be used in astronomical computation into the early twentieth century.Rheticus's fame rests on his connection with Copernicus, and his efforts to get De revolutionibus orbium coelestium published. This is the first edition of his work on triangles, a set of comprehensive set of tables using all six trigonometric functions for use in angular astronomical measurements. The work was unfinished at his death in 1574, but the publication of Rheticus's work was accomplished by his pupil Valentin Otho (c. 1545-1603), eventually seeing the light of day in 1596. These trigonometrical tables (as corrected by Bartholomaeus Pitiscus in 1613) were still in use in the early twentieth century.LITERATURE & REFERENCESVD16 J 278; USTC 679854 (all 6 parts); OCLC Number / Unique Identifier:457809739; Cajori, A History of Mathematics, p. 132-"This was indeed a gigantic work, -a monument of German diligence and indefatigable perseverance ; Brunet IV, 1265 ; Adams R 443 ; Honeymann 2631 ; Sotheran suppl.
