Trying to understand a concept on vector calculus, the book states:
If S is a surface represented by
[tex]\textbf{r}(u,v) = u\textbf{i} + v\textbf{j} + f(u,v)\textbf{k}[/tex]
Any curve r(λ), where λ is a parameter, on the surface S can be represented by a pair of equations relating the parameters u and v, for example u = f(λ) and v = g(λ).
What exactly is the justification or proof for this statement?
