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

1.设 (dfrac (1)(x))=x((dfrac {x)(x+1))}^2, 则 f(x)= ()-|||-(A) dfrac (1)(x)((dfrac

将函数(x)=dfrac (1)(x+1)展开成(x-1)的幂级数2.计算(x)=dfrac (1)(x+1),其中(x)=dfrac (1)(x+1)是锥面(

设(x)+(x)^2f(dfrac (1)(x))=dfrac ({x)^2+2x}(x+1) 求f(x)设

(x)=dfrac ({x)^2-1}((x+1)(x-2))

44.设 (x)=f(x)(dfrac (1)({2)^x+1}-dfrac (1)(2)), 已知f(x)为奇函数,判断F(x)的奇偶性.

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