In this volume, which was originally published in 1931, Hobson focuses on the forms and analytical properties of the functions which arise in connection with those solutions of Laplace's equation which are adapted to the case of particular boundary problems...read more

Product Description: This account of the theory of the circular functions and their applications to plane trigonometry begins with the measurement of angular magnitude and of lines, and proceeds to circular functions, the expansion of functions of multiple angles, trigonometrical tables, the solution of triangles, and properties of triangles and quadrilaterals...read more
