I Definition:The order of a differential equation is the order of the highest ordered derivative that appears in the given equation. The degree of a differential equation is the degree of the highest ordered derivative treated as a variable. I Examples: (a) @2u @x2 + @2u @y2 = 0 is of order 2 and degree 1 (b) (x2 +y2)dx 2xydy = 0 is of order 1 ...

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
