A differential equation (de) is an equation involving a function and its deriva-tives. Differential equations are called partial differential equations (pde) or or-dinary differential equations (ode) according to whether or not they contain partial derivatives. The order of a differential equation is the highest order derivative occurring.

Class 12 Maths Chapter 9 Differential Equations Formulas – PDF Download. A differential equation is a mathematical equation that relates some function with its derivatives. In applications, the functions usually represent physical quantities, the derivatives represent their rates of change, and the equation defines a relationship between the two.
