PREFACE
This book is a continuation of the author’s Calculus, Volume I, Second Edition. The
present volume has been written with the same underlying philosophy that prevailed in the
first. Sound training in technique bined with a strong theoretical development.
Every effort has been made to convey the spirit of modern mathematics without undue
emphasis on formalization. As in Volume I, historical remarks are included to give the
student a sense of participation in the evolution of ideas.
The second volume is divided into three parts, entitled Linear Analysis, Nonlinear
Ana!ysis, and Special Topics. The last two chapters of Volume I have been repeated as the
first two chapters of Volume II so that all the material on linear algebra will plete
in one volume.
Part 1 contains an introduction to linear algebra, including linear transformations,
matrices, determinants, eigenvalues, and quadratic forms. Applications are given to
analysis, in particular to the study of linear differential equations. Systems of differential
equations are treated with the help of matrix calculus. Existence and uniqueness theorems
are proved by Picard’s method of essive approximations, which is also cast in the
language of contraction operators.
Part 2 discusses the calculus of functions of several variables. Differential calculus
