ODEs are essential in modeling continuous dynamic systems in various fields
ODEs involve derivatives with respect to one independent variable, while partial differential equations involve derivatives with respect to more than one independent variable
ODEs enable the prediction of system behavior over time, making them indispensable in analyzing mechanical vibrations, population growth, electrical circuits, and market fluctuations
ODEs relate a function to its derivatives, and their order is determined by the highest derivative they contain
Solutions to ODEs can be expressed in a closed form (explicit) or defined by an equation (implicit)
Analytical methods, such as separation of variables and the method of integrating factors, yield exact solutions, while numerical methods, like the Euler and Runge-Kutta methods, approximate solutions when exact expressions are not feasible
The order of an ODE is based on the highest derivative it contains, with first-order ODEs involving only the first derivative, second-order ODEs including the second derivative, and so on
Linear ODEs have solutions that can be added together or multiplied by constants to produce new solutions, while non-linear ODEs may involve more complex terms
Homogeneous ODEs consist solely of the dependent variable and its derivatives, while non-homogeneous ODEs include additional functions
