Understanding Differential Equations
Differential equations are mathematical equations that relate a function to its derivatives. They are essential for modeling dynamic systems where variables change over time or space. There are two main types of differential equations:
- Ordinary Differential Equations (ODEs): These equations involve functions of a single variable and their derivatives.
- Partial Differential Equations (PDEs): These equations involve multiple independent variables and their partial derivatives.
Differential equations are categorized into linear and nonlinear equations, with each category having its own solution techniques and applications.
