设2f(x)+xf(1/x)=x+1,则f(x)=? 设2f(x)+xf(1/x)=(x+2x)/(x+1),求f(x). 设f(x)满足2f(x)+xf(1/x)=x+1,则f(1/x)=_______ 设f(x)=2x^2-2xf'(1),则f'(1)= 设f(x)满足∫[0,x]t^2f(tx)dt=xf(x)-1,求f(x) 设函数f(x)在R上的导函数为f'(x),且2f(x)+xf'(x)>x^2,则下列不等式在R内恒成立的是A.xf'(x)>0B.xf'(x)=0 设函数f(x)的导数为f'(x),且f(x)=x^2+2xf'(1),则f'(0)= 设函数f(x)的导函数为f'(x) 且f(x)=x^2+2xf'(1)则f'(0)= 设f(x)=3x^2-3xf'(x)+1,则f'(1)=?,f(1)=?应该是f(x)=3x^2-3xf'(1)+1 设函数f(x)连续,则d∫xf(x^2)dx=? 设f(x)连续 则d∫(0,2x)xf(t)dt/dx=? ∫(0-2x)1/xf(t/2)dt f(x)=xf'(x), 设f''(x)在[0,1]上连续,f'(1)=0,且f(1)-f(2)=2,则∫(0,1)xf''(x)dx= y=f(-x^2),则y'=A xf'(-x^2)B -2xf'(-x^2)C 2f'(-x^2)D 2xf'(-x^2) 设∫f(x)dx=F(x)+C,则∫xf(ax^2+b)dx=? 设奇函数f(x)在零到正无穷上为增函数,若f(-2)=0则不等式xf(x) 15.设f(x)为奇函数,且在(-∞,0)内是减函数,f(-2)= 0,则xf(x) 设f(x)为奇函数,且在（-∞,0）内是减函数,f(-2)=0,则xf(x)
