In 1841 Gregory published his Examples of the Processes of the Differential and Integral Calculus, a work which produced a great change for the better in the Cambridge mathematical books. It is the first in which constant use is made of the method known by the name of the separation of the symbols of operation, and the author has enlivened its pages by occasionally introducing historical notices of the problems discussed... His other mathematical work was A Treatise on the Application of Analysis to Solid Geometry, which was left unfinished at his death, and was completed and published by Walton in 1845. This is the first treatise in which the system of solid geometry is developed by means of symmetrical equations, and is a great advance on those of Leroy and Hymers. (en) |
