Discussion on the Definite Integral Calculation Methods and Techniques
Abstract：In the definite integral computation on the base of formula Newton - Leibniz formula and calculate definite integral common methods：integration by parts and substitution method，summarized the definite integral calculation method in a particular interval of some natural integrand, and has been proven theorem to calculate definite integrals，definite integral is often ignored in the calculation of skills，thereby reducing the amount of computation, and improve the efficiency of operations.
