N/A

3. The attempt at a solution

Okay, my plan of attack to get du/dx was to solve t in terms of x in one equation, solve s in terms of x in the other and all sub intio the original equation and that the derivative with respect to x.

I can solve t in terms of x,

[tex]t = \frac{4}{x^3+x^2}[/tex]

However, I'm having trouble doing the same for s. This is about as far as I can get,

[tex]s = ln\left(s^3x^2 - 1\right)[/tex]

Does anyone have any suggestions?
