The ranges of and as given by eq. (2.17) are not the only possible ones.

The ranges of θ and φ as given by eq. (2.17) are not the only possible ones. The following are all alternative ranges of θ and φ, except

(a) 0 ≤ θ < 2π, 0 ≤ φ ≤ π
(b) 0 ≤ θ < 2π, 0 ≤ φ < 2π
(c) - π ≤ θ ≤ π, 0 ≤ φ ≤ π
(d) - π/2 ≤ θ ≤ π/2, 0 ≤ φ < 2π
(e) 0 ≤ θ ≤ π, - π ≤ φ < π
(f) - π ≤ θ < π, - π ≤ φ < π
