(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

If y=f(u) and u=g(x)

f and g are differentiable; show that

d^2y/dx^2=d^2y/dx^2(du/dx)^2+dy/du(d^2u/dx^2)

2. Relevant equations

f'(x)=df/dx

3. The attempt at a solution

I think the notation is throwing me off, can this be translated in prime notation? And I know y is a compostion of f and g.
