Partial Differential Equations (PDE's) Learning Objectives 1) Be able to distinguish between the 3 classes of 2nd order, linear PDE's. Know the physical problems each class represents and the physical/mathematical characteristics of each. 2) Be able to describe the differences between finite-difference and finite-element methods for solving PDEs.
