Spherical astronomy, or positional astronomy, is a branch of observational astronomy used to locate astronomical objects on the celestial sphere, as seen at a particular date, time, and location on Earth. It relies on the mathematical methods of spherical trigonometry and the measurements of astrometry.

Web3 The pitfall is that there are two values of A between 0 o and 180 o that satisfy sin A = 0.821575, namely 55 o 14'.6 and 124 o 45'.4. Figure III.3 shows that, given the original data, either of these is a valid solution. The lesson to be learned from this is that all inverse trigonometric functions (sin-1, cos-1, tan-1) have two solutions between 0 o and 360 o.
