So say I want to find the metric of a surface, which is obviously 2 dimensions, which is immersed in a 3 dimensional space.(adsbygoogle = window.adsbygoogle || []).push({});

The surface is described by 3 coordinates (x,y,z) in Cartesian, but can be expressed using 2 (r, phi) in polar.

Does this mean you'd end up with a 2 dimensional or 3 dimensional metric?

Thanks.
