Numerical Methods for Ordinary Differential Equations

Many real-world problems in physics, engineering, biology, and finance are modeled using ordinary differential equations (ODEs), but analytical solutions are often impossible to find. This course provides a clear, text-based introduction to the essential numerical methods that allow you to approximate these solutions effectively. You will gain a deep understanding of how these methods work and their practical implications. By the end of this course, you will be equipped to select, apply, and analyze various numerical techniques for solving initial value problems, laying a strong foundation for further study and application in computational modeling. What you'll learn: * Understand the fundamental concepts of ordinary differential equations and the necessity of numerical solutions. * Apply Euler's method and its variations for approximating solutions to initial value problems. * Implement improved single-step methods, including Runge-Kutta (RK2 and RK4), for greater accuracy. * Analyze sources of error, such as truncation and round-off, and assess the stability of numerical schemes. * Extend numerical techniques to solve systems of coupled ordinary differential equations. * Evaluate the trade-offs between accuracy, computational cost, and stability for different numerical approaches. This course begins with core terminology and foundational definitions, progressing through single-step methods, error analysis, and the application of these techniques to systems of ODEs. It is designed for absolute beginners with no prior experience in numerical methods or advanced mathematics beyond basic calculus.
