Differential Equations
Differential Equations are mathematical equations that involve one or more functions and their derivatives. They are used to model relationships between various quantities that are changing over time or space. These equations are important in many fields such as physics, engineering, economics, and biology, as they provide a way to describe and analyze how systems evolve and change. Differential equations can be classified as either ordinary differential equations, which involve only one independent variable, or partial differential equations, which involve multiple independent variables.
