"Infinite series are an important tool in the mathematics of science, and this book is designed to provide students with a self-contained first account of the theory. Although the treatment is elementary (diagrams and illustrative numerical examples are used throughout), the necessary basic concepts, particularly that of the limited of a sequence of numbers, are developed and discussed fully. The second chapter introduces infinite series themselves, convergence, the standard convergence tests (comparison, ratio, integral tests, etc.), absolute convergence, power series, and multiplication of series. The third chapter deals with some further topics, including the numerical evaluation of the sum of a series, integration of power series, Dirichlet's test, and series of complex numbers."
Book in very good condition.
