Pierre W. Orelus,Curry S. Malottrivatives. The equations . and . are both examples of differential equations. The order of a differential equation is the order of the highest derivative of the function . that appears in the equation. Thus (i) is a first-order differential equation and (ii) is a third-order differential equation. B

Explaining the Cross-National Pattern solving Equation (1). This, of course, is very disappointing. However, it is not necessary, in most applications, to find the solutions of (1) explicitly. For example, let ..(.) and ..(.) denote the populations, at time ., of two species competing amongst themselves for the limited food and living
