Composite numerical integral formula is not only the main content of numerical integral theory but also an important method for practical numerical integral solution. According to two general composite integral formulas, i. e. composite trapezoidal formula and composite Simpson formula, This paper uses practical calculation examples to verify the theory for these two methods, analyzes their calculation accuracy and efficiency and provides reference and basis for students and engineers to learn and use composite integral formulas.
