In this book, we are focused on solving the integration problems, one of the most difficult fields of theory of mathematical analysis and solving problems. People who learn or teach mathematical analysis know that, however the integrability of the integrand is well known, static integral calculations are generally difficult because of the nonexistence or inability of the primary function to calculate. Therefore, finding more effective and practical computing formulas or techniques for calculating definite integrals is an important way to enrich the content of mathematical analysis and solve...
