The principles of partial differential equations, as applied to typical issues in engineering and the physical sciences, are examined and explained in this preliminary work. The text focuses on engineering and the physical sciences. In addition to the Cauchy-Kovalevsky theory, integral curves and surfaces of vector fields, and several other topics, Calculus, and ordinary differential equations are reviewed here. It details the issues as well as the possible remedies to those issues.
