| Abstract: | In calculation of definite integral,beginners tend to use three methods of calculation:(1)Leibniz formula,(2)integration by substitution of definite integral,(3)integration by parts of definite integral.These three methods are easy for students.However,some kinds of special type of definite integrals are difficult to calculate.This paper offers some methods and techniques of calculation to deal with some of these special types definite integral to exploit new tracks to solve problems and improve students' computational ability of definite integral. |
