Surveying When a star is between the pole and the horizon, the relationship between latitude (λ), zenith distance (z) and declination δ, is θ = z + δ θ = 180° - (z + δ) θ = δ - z θ = (z + δ) - 180° θ = z + δ θ = 180° - (z + δ) θ = δ - z θ = (z + δ) - 180° ANSWER DOWNLOAD EXAMIANS APP
Surveying If α, H, A and δ be the altitude, hour angle, azimuth and declination of a circumpolar star at its elongation, in latitude λ, the following relation holds good sin A = cos δ/cos λ sin α = sin λ/sin δ All listed here cos H = tan λ/tan δ sin A = cos δ/cos λ sin α = sin λ/sin δ All listed here cos H = tan λ/tan δ ANSWER DOWNLOAD EXAMIANS APP
