1 First Order Partial Differential Equations The profound study of nature is the most fertile source of mathematical discover-ies. - Joseph Fourier (1768-1830) begin our study of Partial Differential equationswithfirstorder Partial Differential doing so, we need to define a (see the appendix on Differential Equations ) that ann-th orderordinary Differential equation is an equation for an unknown functiony(x)n-th Order ordinary Differential equationthat expresses a relationship between the unknown function and its firstnderivatives. One could write this generally asF(y(n)(x),y(n 1)(x).)
