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
Surveying If v, t and f/H are the ground speed of the aircraft, the shutter speed of the camera and the scale of the photograph respectively, then the amount of image displacement i = t. H/v. f i = v. t. (f/H) i = v. t. H/f i = v. f/t. H i = t. H/v. f i = v. t. (f/H) i = v. t. H/f i = v. f/t. H ANSWER DOWNLOAD EXAMIANS APP
