Mar 08, 2014 · Partial Differential Equations I: Basics and Separable Solutions We now turn our attention to differential equations in which the “unknown function to be deter-mined” — which we will usually denote by u — depends on two or more variables. Hence the derivatives are partial derivatives with respect to the various variables.
