express [tex](\frac{\partial u}{\partial s})_{v}[/tex] in terms of partial derivatives of u(s,t) and t(s,v)

2. Relevant equations

3. The attempt at a solution

I'm pretty stuck with this problem. I know that

dv = [tex](\frac{\partial v}{\partial s})_{t} ds + (\frac{\partial v}{\partial t})_{s} dt[/tex]

and similarly for u(s,t) and t(s,v). But problem is that where do I get [tex](\frac{\partial u}{\partial s})_{v}[/tex] from, and how to express it?
