Foundational Numerical Methods for Science and Engineering

When analytical mathematical solutions are impossible or impractical, numerical methods provide the essential tools to find precise, approximate solutions. This text-based course guides you through the fundamental algorithms used to solve complex mathematical problems computationally. You will transition from theoretical mathematical concepts to practical computational approximations. By reading through detailed derivations and structured examples, you will understand how calculators and computer software solve algebraic equations, perform integration, and compute differential equations behind the scenes. What you'll learn: Understand the core concepts of numerical errors, floating-point representation, and approximation limits; Solve algebraic and transcendental equations using methods like Bisection and Newton-Raphson; Apply numerical integration techniques, including the Trapezoidal Rule and Simpson's Rules, to approximate definite integrals; Derive and execute numerical solutions for ordinary differential equations using the Runge-Kutta method; Analyze the convergence and stability of different numerical algorithms to choose the right tool for any mathematical problem. The course begins with foundational definitions of error analysis and approximation theory before walking you through step-by-step mathematical derivations and practical, text-based implementation exercises. Designed for beginner engineering students, science majors, and self-taught programmers looking to build a strong mathematical foundation in computational methods, with no prior advanced calculus required.
