Abstract
Have you tried to create your own trigonometric tables and
thus join the likes of several mathematician astronomers
of the past who created tables of trigonometric functions
for their astronomical calculations? Sine tables in Bhāskarācārya’s SiddhāntaŚiromaṇi The great 12th century Indian mathematician and astronomer, Bhāskarācārya II, describes the creation of sine tables in his
magnum opus, the SiddhāntaŚiromaṇi, in a section named
Jyotpatti [1]. The very name Jyotpatti means ‘jyānām utpattiḥ’, i.e., creation or generation of sine tables. Jyotpatti is a part of Golādhyāya (dealing with Trigonometry), which is one of the four major parts of the SiddhāntaŚiromaṇi, the other three being Līlāvatī (dealing with Arithmetic), Bījagaṇita (dealing with Algebra)
and Grahagaṇita (dealing with Planetary Motion)
