This course is a continuation of Differential Equations and is a combination of selected analytical and numerical methods of solutions to problems commonly encountered in chemical engineering. Laplace Transforms and Fourier Series are discussed as a tool in solving ordinary and partial differential equations analytically. Numerical Methods are applied in determining roots of non-linear equations, integration, differentiation and solutions of ordinary and partial differential equations. Knowledge of computer programming or the use of commercial softwares is essential to facilitate repetitive numerical calculations.
