求不定积分int dfrac (1)(2x)sqrt (ln x)dx=（）.int dfrac (1)(2x)sqrt (ln x)dx=int dfrac

int dfrac (1)(x{ln )^2x}dx

下列计算错误的是 （）。A int dfrac (1)(x)dx=ln |x|+C B int dfrac (1)(x)dx=ln |x|+C C int df

int dfrac (x-1)({x)^2+2x+3}dx

5.计算下列不定积分:-|||-(1) int dfrac (ln x-1)({x)^2}dx ;

求：int dfrac (1-ln x)({(x-ln x))^2}dx求：

(int )_(1)^(e^2)dfrac (ln x)(sqrt {x)}dx= __

int dfrac ({x)^2+1}({(x+1))^2(x-1)}dx；；

int dfrac (ln x)({(1+{x)^2)}^3/2}dx; ;

(43 ) int dfrac (x-1)({x)^2+2x+3}dx ;
