口诀在分部积分法求解不定积分中的应用

The Application of Formula in Solving Indefinite Integral in Partial Integral Method

利用"三指动,反对不动"的口诀求解不定积分,降低了分部积分法的难度,提高了分部积分法的运算效率,有利于学生记忆求解方法并灵活运用。

This paper used a pithy formula of 'trigonometric and exponent function move, anti-trigonometric function and logarithmic function dose not move' to solve indefinite integral. It reduced the difficulty of partial integration method and improved the operation efficiency of partial integration method. The pithy formula can facilitate students to memory this method. To using this pithy formula students can solve partial integration method flexible.
