Covariant and contravariant components

Click For Summary
SUMMARY

The discussion focuses on calculating the covariant and contravariant components of the metric tensor for the two-dimensional space defined by the metric ds² = e^y dx² + e^x dy². It is established that the covariant components are not simply e^y and e^x; rather, both covariant and contravariant tensors consist of four components each, totaling eight components. The correct approach requires a thorough understanding of tensor calculus and the specific metric structure provided.

Homework Statement



Consider the two-dimensional space given by

ds^2 = e^y dx^2 + e^x dy^2

Calculate the covariant and contravariant components of the metric tensor for this
spacetime.


The Attempt at a Solution



Are the covariant components just e^y and e^x with the contravariant components being 1/e^y and 1/e^x?

You are missing some components.
 
Both tensors have 4 components. You should come up with 8 numbers altogether.
