Given a regular surface $S \subseteq \mathbb{R}^3$, a point $p \in S$ and a basis $\{v_1,v_2\}$ of the tangent plane $T_P(S)$, I want to prove the existence of a parameterization $\varphi: U \to S$ centered at $p$ for which $\frac{\partial \varphi}{\partial u}=v_1$ and $\frac{\partial \varphi}{\partial v}=v_2$.
I tried to give an argument in Existence of a parameterization whose differential has columns $v_1,v_2 \in T_p(S)$
However, I'm not sure it is correct. May you help me, please?
