Book Description

Excerpt from Bell's Mathematical Tables: Together With a Collection of Mathematical Formulae, Definitions, and Theorems It is to be regretted that for reasons of space it was found impracticable to include a separate section on differential equations, these important equations being only dealt with in connection with special functions, as in the sections on elliptic functions, spherical harmonics, and Bessel functions. Some readers will miss also, though to a lesser degree, the integral equations and, perhaps, a host of other important details. But notwithstanding all these omissions it is hoped that the volume will, to a good extent, cover the every-day needs of many readers. The writer will be glad to take account, in a future edition, of all complaints, corrigenda, requirements, and new recommendations, which the readers are fervently requested to send either to his or the publishers' address. It is hoped that with such frank and generous co-operation the book may be readily improved and gradu ally shaped so as to cover exactly the actual needs of the readers. My thanks are due to my friends, Professor Alfred W. Porter and Professor E. N. Da C. Andrade of London, and to Professor L. V. King of Montreal, for many valuable hints, and for reading part of the ms.; and to the publishers for the care they have bestowed upon my work.
