Differential equation - Wikipedia
https://en.wikipedia.org/wiki/Differential_equationIn mathematics, a differential equation is an equation that relates one or more functions and their derivatives. In applications, the functions generally represent physical quantities, the derivatives represent their rates of change, and the differential equation defines a relationship between the two. Such relations are common; therefore, differential equations play a prominent role in many discip…
