## Introduction to Numerical Methods Lecture Notes PDF

Numerical methods lecture notes: Numerical methods are sets of mathematical techniques and tools used for the purpose of solving complex numerical problems. These methods are useful in efficiently tackling mathematical problems for which getting an exact solution is difficult. Algorithms are used to draw numerical approximations for complex world problems. Numerical methods are a type of “trial-and-error” process. Numerical methods involve finding basic problem solutions of integration and linear equations to advance problem solving for “finite element method”.
