I'm slightly confused with this problem:

$\displaystyle x(t) = t^3 + 3t + 1 $ & $\displaystyle y(t) = ln(3t^2 - 3) $

Find the function $\displaystyle p(t)$ such that:

$\displaystyle \frac{d^2y}{dx^2} = p(t)\frac{d^2y}{dt^2}\frac{d^2t}{dx^2}$

I'm new to this subject so any help would be really appreciated.
