Numerical Methods (2nd Edition)

In numerical analysis, a numerical method is a mathematical tool designed to solve numerical problems. Numerical methods provide approximations to the problems in question. No matter how accurate they are they do not, in most cases, provide the exact answer. In some instances working out the exact answer by a different approach may not be possible or may be too time consuming and it is in these cases where numerical methods are most often used. The implementation of a numerical method with an appropriate convergence check in a programming language is called a numerical algorithm.
The Second Edition of Numerical Methods is designed to explore the coverage of algorithms, polynomial approximation, numerical solution of differential equations, exponential approximation, testing of hypothesis, and other topics.
