定积分求导问题,划线部分是怎么推出来的呢?感谢

定积分证明,答案中我划线的部分最后取大于二分之一,取二分之一是否是数学证明中的一个习惯?取三分之一_百度知道

可以这么理解,他只要存在实数在(0 1)都可以取,因为他的尾部x都是趋于无穷的。

出门在外也不愁高数定积分问题,我划线的两个式子是怎么化简的?_百度知道
提问者采纳
tanu在积分范围内是奇函数,所以,当积分范围对称时,积分为零
tanu^2在对称积分范围内为偶函数,所以积分等于2倍的正数范围内积分
能明白吗?
我再看看啊~

dy/dv=mv/(H-kv)=(m/k)(kv/(H-kv))=(m/k)(H-H+kv/(H-kv))=mH/k(H-kv)-m/k这样就可以积分了
我明白了!谢谢~~
