Numerical Techniques

In practical real life engineering designs, we often come across problems which consist of numerical operations such as integration or differentiation. For example, in a standard tracing of a robotic arm, the computation of the total error involves integration of instantaneous errors. While mathematical problems require analytic solutions which are sometimes very hard or impossible to obtain, most engineering problems require only numerical solutions. Sometimes the variation of values with parameters is considered sufficient instead of actually finding the closed form relation in terms of parameters. Such a method ...
