INTRODUCTION TO SPHERICAL TRIGONOMETRY: PART 1
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 trigonometric functions. On the sphere, geodesics are great circles. Spherical trigonometry is of great importance for … See more Spherical polygons A spherical polygon is a polygon on the surface of the sphere. Its sides are arcs of great circles—the spherical geometry equivalent of line segments in plane geometry See more Supplemental cosine rules Applying the cosine rules to the polar triangle gives (Todhunter, Art.47), i.e. replacing A by π – a, … See more Consider an N-sided spherical polygon and let An denote the n-th interior angle. The area of such a polygon is given by (Todhunter, Art.99) See more • Weisstein, Eric W. "Spherical Trigonometry". MathWorld. a more thorough list of identities, with some derivation See more Cosine rules The cosine rule is the fundamental identity of spherical trigonometry: all other identities, including the sine rule, may be derived from the cosine rule: $${\displaystyle \cos a=\cos b\cos c+\sin b\sin c\cos A,\!}$$ See more Oblique triangles The solution of triangles is the principal purpose of spherical trigonometry: given three, four or five elements of the triangle, determine the others. The case of five given elements is trivial, requiring only a single application of … See more • Air navigation • Celestial navigation • Ellipsoidal trigonometry See more WebIn this video, we discuss the topic of Spherical Geometry & Trigonometry.
