WebThe Riemann curvature tensor is also the commutator of the covariant derivative of an arbitrary covector with itself:;; =. This formula is often called the Ricci identity. This is the classical method used by Ricci and Levi-Civita to obtain an expression for the Riemann curvature tensor. This identity can be generalized to get the commutators for two … WebGiven that the radius of Earth is 6371km, we can find. θ = s r = 1 k m 6371 k m = 1 6371 r a d = 1.56 ∗ 10 − 4 r a d. I think h could found by. h = 6371 sin ( π 2) − 6371 sin ( π 2 − 1.56 ∗ 10 − 4) = 7.84 ∗ 10 − 5 k m. which …
