Numerical Methods and Computational Math for Beginners

When analytical mathematical methods fail, computational algorithms step in to solve complex real-world problems. This course introduces you to the essential concepts of numerical analysis and computational linear algebra, bridging the gap between pure mathematics and practical computer science. You will learn how computers represent numbers, handle rounding errors, and execute iterative algorithms to find precise approximations. By the end of this text-only course, you will understand how to translate mathematical theories into structured, executable code. You will be able to solve systems of linear equations, find roots of non-linear functions, perform numerical integration, and apply these methods to real-world data scenarios. What you'll learn: Understand mathematical error analysis, floating-point representation, and numerical stability; Solve systems of linear equations using direct and iterative computational methods; Find roots of non-linear equations using bisection and Newton-Raphson algorithms; Interpolate data points and construct approximating polynomials; Perform numerical differentiation and integration using computational rules; Practice writing clean, modern Python code using numpy to automate mathematical calculations. We begin with foundational definitions of error propagation and computer arithmetic before moving step-by-step through algebraic solvers, interpolation, and calculus approximations. This course is designed for beginners, students, and aspiring data professionals who want to understand the mechanics of computational math without requiring advanced programming prerequisites.
