摘要
通过实例说明第二换元积分法使用三角代换对夹角范围的限制,没有缩小被积函数的定义域的范围.
The paper explains with examples the limits on the degrees of intersectional angle in calculating indefinite integral by using trigonomentrical substitutions which belong to the second mathematical manipulation, and this operation doesn＇t change the definition of the function
