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.
