It won't let me upload my image. Says I need to contact an admin

G(x)=3x * (1-2x^2)^-1/3 See attached photo for my proof, I'm sure its not right.

Homework Statement (1-2x3+x2)((1/x3)+1) Homework Equations f'g(x)+g'f(x) f'(x)=-6x3+2x g'(x)=(-1/x4) The Attempt at a Solution I found what i believe to be the derivative of both f(x) & g(x) and used the product rule to get to where I am stuck right now: [(-6x2+2x)(1/x3)]+[(-1/x4)(1-2x3+x2)

Sorry for not showing my work on my last post, I'm on my good for nothing blackberry and apparently cannot type. My question was: Use first principles definition to find dy/dx: y=(-4/3x) lim x--> 0 --------- (X,-4/3x) (X+h, -4/3(X+h) =lim»0 ((-4/3(x+h))-(-4/3x))/x+h-x I have...
