In differential geometry, how can one show that the area form: √(EG-F(adsbygoogle = window.adsbygoogle || []).push({}); ^{2})du[itex]\wedge[/itex]dv is independent of the choice of local parameterization?

Here E,F,G are the coefficients of first fundamental form. Please someone gives me some ideas.
