Hi, by saying "covariant metic" I mean writing the metric in its covariant form - basically g(contra)=[g(cov)]^(-1) you can use the metric to lower/raise an index on a vector component but here e_j and e^k are not components but the actual unit vectors.

Homework Statement e_j=g_(jk)e^k where e_j is a covariant vector base e^k is a a contravariant vector base g_(jk) is the covariant metric Homework Equations The Attempt at a Solution
