ABSTRACT
In many situations, due to the complexity of integrands and irregularity of the domain in definite integrals it becomes necessary to approximate the value of the integral. The numerical integration methods or quadrature methods are methods of obtaining approximate values of the definite integrals. Many simple numerical integration methods are derived using the simple fact that if we wish to calculate the integral of f(x) between the limits x = A to x = B, i.e., () I = ∫ A B f ( x ) d x https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429028281/78e5907e-74ed-4838-87b2-471740f93432/content/eq1652.tif"/>
