I have a metric given as a line element differential ds^2. I have written down the 3x3 matrix with the coefficients. I am then asked to determine "g" (which I think i just did by enumerating the matrix) and "g^ij", which I normally would assume means the same thing, but apparently not.(adsbygoogle = window.adsbygoogle || []).push({});

So what exactly is the difference?

Many thanks,
