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 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
