Spherical Trigonometry For Navigation

Spherical Trigonometry For Navigation. The subject is practical, for example, because we live on in contrast to plane trigonometry, the sides of a spherical triangle are themselves angles, and so we can take sines and cosines etc. • in navigation applications the angles and sides of spherical triangles have specific meanings.
