Foundations of Numerical Methods and Analysis

When analytical mathematical methods fail to find exact solutions to complex real-world problems, numerical methods provide the essential computational tools to find highly accurate approximations. This text-only course guides you from the fundamental mathematical concepts of approximation and error analysis to implementing powerful numerical algorithms. You will build a solid foundation in solving algebraic equations, interpolation, numerical integration, and differential equations, while exploring how these concepts translate into modern computational workflows. What you will learn: - Understand the core concepts of truncation errors, round-off errors, and algorithm stability. - Solve non-linear equations using methods like bisection, secant, and Newton-Raphson. - Apply interpolation techniques and polynomial approximations to estimate missing data points. - Perform numerical differentiation and integration using trapezoidal and Simpson's rules. - Solve ordinary differential equations using Euler's and Runge-Kutta methods. - Explore modern computational practices, including vectorization concepts and algorithmic efficiency. You will start with key mathematical definitions and error analysis before moving step-by-step through core numerical techniques. Each concept is explained through clear text, step-by-step derivations, and practical algorithmic walkthroughs. This course is designed for beginners in mathematics, physics, engineering, and computer science who want a structured, text-based introduction to numerical analysis, with no prerequisites required.
