But when I calculate Γ 12 2 I get − sin θ cos θ, which apparently is incorrect and should be − tan θ.
In short, Christoffel symbols are symmetric in the two lower indices, meaning that these indices can be interchanged freely (Γ λ µν =Γ λ νµ). This is due to the fact that Christoffel symbols are defined as connection coefficients for a torsion-free connection, which requires them to be symmetric.
