不定积分x^2/(x-1)^100dx=?
不定积分x^2/(x-1)^100dx=?
分子减去加上一个一,变成x+1/(X-1)^99+1/(X-1)^100=1/(x-1)^98+2/(x-1)^99+1/(x-1)^100dx-1
分子配出(x-1)^2
∫x^2/(x-1)^100dx=1/101∫x^2d(x-1)^101=1/101[x^2(x-1)^101-∫(x-1)^101dx^2]=1/101[x^2(x-1)^101-2∫x(x-1)^101dx]=1/101[x^2(x-1)^101-2/102∫xd(x-1)^102]=1/101[x^2(x-1)^101-2/102[x(x-1...
-x^2/(99(x-1)^99)-x/(4851(x-1)^98)-1/(470547(x-1)^97)+c
令t=x-1:然后变为 (t+1)^2/t^100dt = t^-98+2t^-99+t^-100 dt = -1/97*t^-97-2/98*t^-98-1/99*t^-99 再带回去 = =
x^2/(x-1)^100=(x^2-1+1)/(x-1)^100=(x+1)(x-1)/(x-1)^100+1/(x-1)^100=(x+1)/(x-1)^99+1/(x-1)^100=(x-1+2)/(x-1)^99+1/(x-1)^100=1/(x-1)^98+2/(x-1)^99+1/(x-1)^100故积分x^2/(x-1)^100dx=积分[1/(x-1)^98+2/(x-1)^99+1/(x-1)^100]dx=-1/97*1/(x-1)^97-1/49*1/(x-1)^98-1/99*1/(x-1)^99+C
令T=X-1,则有:X=T+1,dX=dT上式变为:x^2/(x-1)^100dx=(T+1)^2 /T^100 dT=(T^2+2T+1)/T^100 dT=(T^(-98)+2T^(-99)+T^(-100))dT=-1/97 *T^(-97)-1/49*T^(-98)-1/99*T^(-99)+Clnx的不定积分???????_百度知道
