General First-Order Differential Equations and Solutions A first-order differential equation is an equation (1) in which ƒ(x, y) is a function of two variables defined on a region in the xy-plane. The equation is of first orderbecause it involves only the first derivative dy dx (and not higher-order derivatives). We point out that the equations

First Order Partial Differential Equations “The profound study of nature is the most fertile source of mathematical discover-ies.” - Joseph Fourier (1768-1830) 1.1 Introduction We begin our study of partial differential equations with ﬁrst order partial differential equations. Before doing so, we need to deﬁne a few terms.
