Study Notes

Types of Differential Equations

Ordinary Differential Equation (ODE): Involves functions of a single independent variable and their derivatives.
Partial Differential Equation (PDE): Involves unknown functions of multiple independent variables and their partial derivatives.
Systems of Differential Equations: Consists of interconnected differential equations involving several dependent functions.

Key Terms

Order: Defined by the highest derivative present in the differential equation, determining its complexity.
Linear ODE: Can be expressed as a linear combination of the dependent variable and its derivatives, with coefficients being functions of the independent variable.
Nonlinear ODE: Cannot be expressed as a linear combination of the dependent variable and its derivatives, indicating a more complex relationship.

Solutions

Solution on an interval (a, b): A function that satisfies the ordinary differential equation for all values of the independent variable within the specified interval.
