Differential Equation

A differential equation states how a rate of change (a "differential") in one variable is related to other variables.

In WIKIPEDIA ,
              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. Because such relations are extremely common, differential equations play a prominent role in many disciplines including engineering, physics, economics, and biology..
