Before solving problems, recall the three primary rules of spherical trigonometry applied to the celestial sphere (where sides are arcs of great circles, measured in degrees or time). This public link is valid for 7 days

Mastering this subject requires navigating coordinate systems, understanding the effects of time, and correcting for atmospheric phenomena. This article covers fundamental problems in spherical astronomy and provides practical, mathematical solutions. 1. The Celestial Sphere and Coordinate Systems Can’t copy the link right now

Then determine (A) uniquely: If (\sin A > 0), (A) in (0°–180°); if (\sin A < 0), (A) in (180°–360°). Or use atan2.
