德国纳粹女兵割奶:∫x^n dx=（x^(n+1)）/（n＋1）＋C or ∫x^n dx=（x^(n+1)）/n which is true?why?

4楼那位
我好像没有语法错误吧

有语法错误的应该是2楼吧
,(when n isn's equal to -1).

我用中文来回答吧，这是一个不定积分，原函数不止一个，且它们之间差一个常数，所以一定要有'C'，n不等于-1时，对x^(n+1)）/（n＋1）求导，恰为x^n，所以∫x^n dx=（x^(n+1)）/（n＋1）＋C，又n=-1时，对ln(x)求导，为1/x，所以∫（1/x） dx=ln(x)＋C 。

the first one
just because dC/dt=0 so that we can't be sure whether there is any C ^_^

∫x^n dx=（x^(n+1)）/（n＋1）＋C
this one is partially true,(when n isn's equal to -1).When n=-1,the right solution is "ln(x)+c".

∫x^n dx=（x^(n+1)）/n
this equation is totally wrong. Not only because the lack of 'C'，but also it's not right in any times.(it should be '/(n+1)' instead of '/n')

你个垃圾语法错误了,TRUE是表示真假,对错因该是RIGHT OR WRONG!!!!!!!!!!

怎么都是乱码看不懂

好搞笑啊

∫x^n dx=（x^(n+1)）/（n＋1）＋C or ∫x^n dx=（x^(n+1)）/n which is true?why? ∫x^n dx=（x^(n+1)）/n 是什么意思每项分别代表什么？ x=n*(n+1)*(n+2)*(n+3)....... （x-1)(x^n+x^n-1+……+x+1)= n为正整数 X(n)=-bnu(-n-1) x(5n)+x(n)+1 x^(n-1)+x^(n-2)+x^(n-3)+...+x^(n-n)当n=20，x=2时，结果是多少（-4X^n+1+12X^n-X^n-1)除以（-5X^n-2)等于几 x*(n+3)-3*x(n+2)+3*x(n+1)-x*(n)=0 的解题思路因式分解：(1+x+x^2+.......+x^n)^2-x^n
