If F(x)=∫(e,x)log t dt for all positive x,then F'(x)=?(a)x(b)1/x(c)log x(d)xlog x(e)xlog x-1 ∫[0,x]f(x-t)tdt=e^x-x-1,求f(x) if(m==0) l=-1; t=x-t/m ; else if (t-x-e) l=0; printf(%f %f %f,x,t,k); else x=t; k++;哪里不对 设dy/dx∫(0,e^-x)f(t)dt=e^x,f(x)=? If f(x)=log(x).write out the domain and range of the function. 设连续函数f(x)满足f(x)=e^x-∫(0,x)f(t)dt,求f(x) ∫(0,x)f(t-x)dt=e^(-x²)+1 求f(x)急. f(x)=x^2+∫[0~x]e^（x-t)f '(t)dt 怎么变到 f '(x)=2x+f '(x)+∫[0~x]e^（x-t)f '(t)dt f(x)=e^x+∫(x,0) t f(t) dt - x ∫(x,o) f(t) dt,求f(x) 设二阶可维函数f(x)满足方程[0,x]∫(x+1-t)f'(t)dt=e^x+x^2-f(x),求f(x) 设f(x)为连续函数,且符合关系f(x)=e^x-∫(0,x)(x-t)f(t)dt,求函数f(x) 设f(X)连续且满足 f(x)=e^x+sinx- ∫ x 0 (x-t)f(t)dt,并求该函数f(x)RT 设f(x)连续,且满足f(x)=e^x+∫x上0下（t-x）f（t）dt 求f（x） f(x)=lnx+∫(e,1)f(t)dt,求f(x)? d∫(e^-x～0) f(t)dt/dx=e^x,则f(x)=?d∫(e^-x～0) f(t)dt/dx=e^x,则f(x)= F(x)=∫(x,0)(x-2t)e^(-t^2) 证明:F(x)是偶函数；F(x)在x>0是增函数 F(x)=∫(x,0)(x-2t)e^(-t^2) 证明:F(x)是偶函数；F(x)在x>0是增函数 f（x）=∫（e^t+t)dt(从X积到0）则f’（x）=
