7. Numerical Solution of Ordinary Differential Equations (ODEs)
Numerical methods are essential for solving ordinary differential equations (ODEs) when analytical solutions are impractical. Techniques such as Euler’s Method, Improved Euler’s Method, Runge-Kutta Methods, and Predictor-Corrector Methods provide various approaches, balancing accuracy and computational efficiency. The choice of method depends on the desired precision, available resources, and the specific characteristics of the problem at hand.

What we have learnt
- Differential equations are crucial in modeling physical systems, necessitating numerical methods when analytical solutions are infeasible.
- Various numerical methods such as Euler, Improved Euler, and Runge-Kutta offer trade-offs between simplicity and accuracy.
- Runge-Kutta methods, especially RK4, are favored for their optimal blend of accuracy and computational efficiency.
Key Concepts
- -- Initial Value Problems (IVPs)
- IVPs involve finding the solution of a differential equation given an initial state at a specific point.
- -- Euler’s Method
- A simple numerical approach for approximating solutions to ODEs by using incremental steps based on the function's slope.
- -- RungeKutta Methods
- A group of methods that provide better accuracy for solving ODEs without requiring the small step sizes that Euler's Method demands.
- -- PredictorCorrector Methods
- A numerical approach that first makes an initial guess (predictor) and then refines that guess (corrector) for better accuracy.
