SPHERICAL TRIGONOMETRY Meaning and Definition

1. Spherical trigonometry is a branch of mathematics that deals with the relationships and properties of triangles on the surface of a sphere. It involves the study of angles, sides, and other geometric aspects of spherical triangles.

   In regular trigonometry, which deals with triangles on a flat plane, angles are measured in degrees or radians, and the Pythagorean theorem is used to find the lengths of sides. However, on a spherical surface, angles are measured in spherical degrees or sometimes called steradians, and the Pythagorean theorem doesn't hold true.

   Spherical trigonometry is commonly used in various fields such as astronomy, geodesy, and navigation, where calculations on a curved surface are essential. For example, in astronomy, spherical trigonometry is used to determine the positions and movements of celestial objects. In geodesy, it helps in measuring and describing the Earth's shape. In navigation, spherical trigonometry aids in plotting routes and calculating distances on the Earth's surface.

   The fundamental concepts of spherical trigonometry include the spherical law of sines, the spherical law of cosines, and the spherical law of tangents, which provide formulas and equations to solve for unknown angles and sides of spherical triangles. These laws are derived by considering the relationships between the sides and angles of triangles inscribed on the surface of a sphere.

   Overall, spherical trigonometry provides the necessary tools to perform calculations involving spherical triangles, enabling accurate measurements and analysis on curved surfaces such as the Earth and the celestial sphere.

2. That branch of trigonometry which treats of spherical angles and triangles; music of the spheres, in the anc. astron., the music supposed to result from the motions of the spheres.

Etymology of SPHERICAL TRIGONOMETRY

The word "spherical trigonometry" is derived from two main components:

1. "Spherical": The term "spherical" comes from the Greek word "sphaira" (σφαῖρα), which means "sphere". It describes objects or concepts related to spheres or their properties. In this context, it refers to the study of triangles on the surface of a sphere.

2. "Trigonometry": The term "trigonometry" also has Greek origins. It is derived from the combination of two Greek words, "trigonon" (τρίγωνον) meaning "triangle", and "metron" (μέτρον) meaning "measure". Trigonometry involves the study of the relationships and properties of triangles, particularly the angles and sides.
