Let g be the inverse for the function f(x)=x+x^3.g'(2)=? g'(0)=? g(0)=? g(2)=? Let x>0 d/dx x^x=? 我算是lnx*x^x ∫上面是5 下面是1 ︱x-2︱ dx=? ∫sin反函数x dx=? ∫∞到-∞ 1/1+x^2 dx =? 为神麽是 拍 ? Suppose g is the inverse function of a differentiable function f and let G(x) =1/g(x) . if f(3)=2 and f'(3)=1/9 G'(2)=? ∫1/2+√x dx=? --
