Differential and integro-differential equations, especially nonlinear, present the most effective way for describing complex processes. The book begins with the basic definitions, the physical and geometric origins of differential equations, and the methods for solving first-order differential equations. Both mathematicians employed equations in a differential form in their work but the term “differential equations” is generally attributed to Leibniz.In the 18th century, the differential equation was accepted as a powerful tool in the formulation of problems in physics and mechanics. A differential equation is an equation for a function containing derivatives of that function. In the following example we shall discuss a very simple application of the ordinary differential equation in physics. Application of Differential Equations.
