Simultaneous linear equations are at the heart of everything from structural analysis to economic forecasting. This chapter provides a thorough overview of direct methods, including the classic Gauss-elimination method and its variant, the Gauss-Jordan method. It also introduces matrix inversion techniques, the concept of condition numbers, and the critical issue of ill-conditioned systems, where a small change in input can cause a huge change in the output. To round out the toolkit, iterative methods like the Jacobi, Gauss-Seidel, and Relaxation methods are presented, offering alternatives when dealing with massive systems of equations.

An improved bracketing method that uses linear interpolation to converge faster than the bisection method.
Many real-world problems cannot be solved by simple algebra and require numerical root-finding techniques. This chapter presents a toolkit of iterative methods, from the conceptually simple bisection method to the more powerful (and faster) Secant method, Regula-Falsi method, and Newton's method. The section concludes with strategies for tackling systems of non-linear equations, a common challenge in engineering and scientific modeling.
