ABSTRACT
Engineering is all about problem solving and many problems in engineering can be solved using calculus. Physicists, chemists, engineers, and many other scientific and technical specialists use calculus in their everyday work; it is a technique of fundamental importance. Both integration and differentiation have numerous applications in engineering and science and some typical examples include determining areas, mean and root mean square values, volumes of solids of revolution, centroids, and second moments of area, differential equations and Fourier series. The process of integration reverses the process of differentiation. Integrals containing an arbitrary constant in their results are called indefinite integrals since their precise value cannot be determined without further information. Definite integrals are those in which limits are applied.
