Designed to provide a firm grounding in mathematical methods for chemical engineering practitioners in academic institutions and industry, this volume builds on the reader's previous knowledge of calculus, differential equations and linear algebra. Varma and Morbidelli offer an integrated treatment of linear operator theory from determinants through partial differential equations, and feature extensive chapters on both ordinary differential equations and perturbation methods. Numerous high-quality diagrams and examples from chemical engineering illustrate the textual material and enhance the reader's understanding of complex mathematical systems.
