First Order Partial Differential Equations “The profound study of nature is the most fertile source of mathematical discover-ies.” - Joseph Fourier (1768-1830) 7.1 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.

classification of partial differential equations can be extended to systems of first-order equations, where the unknown u is now a vector with m components, and the coefficient matrices A ν are m by m matrices for ν = 1, 2, …, n. The partial differential equation takes the formEffective January 1, 2010, California law (Chapter 173,

In mathematics, a first-order partial differential equation is a partial differential equation that involves only first derivatives of the unknown function of n variables. The equation takes the form Such equations arise in the construction of characteristic surfaces for hyperbolic partial differential equations, in the calculus of variations, in some geometrical problems, and in simple models for gas dynamics whose solution involves the method of characteristics. If a family of so…

The general solution to the first order partial differential equation is a solution which contains an arbitrary function. But, the solution to the first order partial differential equations with as many arbitrary constants as the number of independent variables is called the complete integral. The following n-parameter family of solutions
