...turn, cos b = cos c cos a + sin c sin a cos B, cos c = cos a cos b + sin a sin b cos C. In words : In a spherical triangle the cosine of any side is equal...the product of the cosines of the other two sides plus the product of the sines of these two sides and the cosine of their included angle. (Compare Plane... | |
