I may have some conceptual misunderstandings, but here is the code
E=EuclideanSpace(3)
c_spher.<r,th,ph>=E.spherical_coordinates()
f_spher=E.spherical_frame()
E.set_default_chart(c_spher)
E.set_default_frame(f_spher)
g=E.metric()
show(g[:])
I was expecting the diagonal elements of the metric to be [1,r^2,r^4*sin(th)^2], but I get [1,1,1]
What I am doing wrong?
