Determining Latitude of a Place using Trigonometry

Astronomy is a natural science that studies celestial objects and phenomena. It applies mathematics, physics, and chemistry, in an effort to explain the origin of those objects and phenomena and their evolution. It is one of the oldest of the natural sciences. The early civilizations in recorded history, such as the babylonoans, greek, Indians, Egyptians, Nubians, Iranians, Chinese, maya and many ancient indigenous peoples of the Americas performed methodical observations of the night sky. Historically astronomy has included disciplines as diverse as astrometry celestial navigation observational astronomy and the making of calendres. Latitude is a geographic coordinate that specifies the north south position of a point on the earth’s surface. A circumpo alar star is a star as viewed from given latitude on earth that never sets below the horizon due to its apparent proximity to one of the celestial poles. In this paper we would propose how circumpolar star on meridian serves as in finding latitude of places and how this concept plays an vital roles in astronomy.
