∫[f(x)/f’(x)-f^2(x)f’’(x)/f’^3(x)]dx

∫[f(x)/f'(x)-f^2(x)f"(x)/f'^3(x)]dx 如题 f(x)=e^x/x,求∫f'(x)dx/1+f^2(x)? f(x)dx是什么意思 若∫ f(x)dx=F(x)+C,∫ f(3x+5)dx= 若f(x)=e^x+2∫(0 1)f(x)dx 求f(x) [f(x)+xf'(x)]dx 求积分∫f'(x)f(x)f(x)f(x)dx f(x)=x^3+x,则∫ (2,-2)f(x)dx的值等于? 求不定积分：∫[f(x)/f′(x)-f²(x)f″(x)/f′(x)³]dx ∫x*f(x)dx=(x^3)lnx+c.求不定积分∫f(x)dx! f(x+2)>=f(x)+2,f(x+3) f(x)在[0,1]连续,f(x)=3x-√(1-x^2)[∫f^2(x)]dx,求f(x)
