Comparison of three quadrature rules

Sometimes, in science and engineering, we need to calculate some definite integrals of the type: It is equivalent to evaluating the area enclosed between the function graph and x-axis, within the interval [a, b]. There are some integrals (like elliptical, Fresnel, etc.) that cannot be expressed in analytical form. In such cases, we have toContinue reading “Comparison of three quadrature rules”
