Foundations of Numerical Mathematics and Methods

Many real-world mathematical problems cannot be solved with exact analytical formulas. This text-based course introduces you to the core principles of numerical mathematics, enabling you to approximate solutions to complex algebraic, differential, and systems of equations with high precision. By working through clear written explanations and structured mathematical exercises, you will develop a strong mental framework for translating continuous mathematical problems into discrete, computer-solvable algorithms. You will gain the confidence to analyze approximation errors and select the most efficient numerical methods for engineering and scientific applications. What you'll learn: - Understand the foundational concepts of floating-point arithmetic and error analysis. - Solve non-linear equations using root-finding algorithms like bisection and Newton-Raphson. - Apply interpolation and polynomial approximation techniques to discrete datasets. - Compute numerical derivatives and integrate functions using trapezoidal and Simpson's rules. - Solve systems of linear equations using direct and iterative numerical methods. - Implement basic numerical algorithms using modern Python programming patterns and type hints. The course begins with essential terminology, basic definitions of approximation errors, and foundational mathematical principles. You will then progress step-by-step through root-finding, interpolation, numerical calculus, and linear systems, culminating in practical algorithmic implementations. This course is designed for beginners, students of science and engineering, and self-taught programmers looking to understand the mathematics behind computational solvers, with no prior advanced numerical analysis experience required.
