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) - 180° θ = δ - z θ = 180° - (z + δ) θ = z + δ θ = (z + δ) - 180° θ = δ - z θ = 180° - (z + δ) θ = z + δ ANSWER DOWNLOAD EXAMIANS APP
Surveying If ‘δ’ is the declination of the Polaris and ‘λ’ is the latitude of the place, the azimuth of the Polaris, is cos (90° - δ)/cos (90° - λ) sin (90° - δ)/sin (90° - λ) cos δ/cos λ tan (90° + δ)/tan (90° + λ) cos (90° - δ)/cos (90° - λ) sin (90° - δ)/sin (90° - λ) cos δ/cos λ tan (90° + δ)/tan (90° + λ) ANSWER DOWNLOAD EXAMIANS APP
