These are approximate methods starting from an initial guess and converging to an exact solution. Gauss- Jacobi and Gauss- Seidel are iterative methods used to solve a system of equations with a larger number of unknowns. According to the problem to be solved, the field of numerical analysis is divided into various disciplines.

Numerical methods are used by engineers and scientists to solve problems. However, numerical methods are just one step in solving an engineering problem. There are four steps for solving an engineering problem, as shown in Figure \(\PageIndex{2.1}\). Figure \(\PageIndex{2.1}\). Steps of solving a problem. The first step is to describe the problem.

Numerical integration . Some Functions are not integrable, meaning that there is no antiderivative for that function. However, this doesn't mean that we cannot approximate the area underneath these Functions (ie find an approximate solution for a definite integral). We do this by splitting the area under the integral into smaller areas (or shapes that closely resemble the area of the integral ...
