Spherical trigonometry is the branch of spherical geometry that deals with the metrical relationships between the sides and angles of spherical triangles, traditionally expressed using …

To derive the basic formulas pertaining to a spherical triangle, we use plane trigonometry on planes related to the spherical triangle. For example, planes tangent to the sphere at one of …

Jul 23, 2025 · The study of the relationships between the sides and angles of triangles drawn on a sphere's surface is known as spherical trigonometry. By using trigonometric concepts in non …

Nov 14, 2025 · Let a spherical triangle be drawn on the surface of a sphere of radius R, centered at a point O= (0,0,0), with vertices A, B, and C. The vectors from the center of the sphere to …

The circular parts of a right-angled spherical triangle are five, namely, the two sides, the complement of the hypothe- nuse, and the complements of the two angles (the right angle …

In spherical trigonometry, earth is assumed to be a perfect sphere. One minute (0° 1') of arc from the center of the earth has a distance equivalent to one (1) nautical mile (6080 feet) on the arc …

This video is an introduction to spherical trigonometry. I give the basic concepts and derive the spherical version of the Law of Cosines and Law of Sines.

Spherical trigonometry is the study of curved triangles, triangles drawn on the surface of a sphere. The subject is practical, for example, because we live on a sphere.

In summary, spherical trigonometry serves as an essential mathematical framework for analyzing and solving problems related to spherical surfaces, making it indispensable in fields that …
