Problem
Calculate the coordinate basis vectors ea′ of the coordinates system x′a in Exercise 2.3 in terms of the coordinate basis vectors ea of the Cartesian system. Hence verify that the metric functions gab′ agree with those found earlier. Calculate the dual basis vectors e′a in the primed system and hence the quantities g′ab. Find the contravariant and covariant components of e1 in the primed basis. Hence verify that e1 is of unit length.
