Tables of Constants
Some of the Tables of Constants have been given in an
earlier chapter. We here give a few more tables which would
indicate how far Brahmagupta introduced new concepts in eva-
luating these constants of greater accuracy and refinement.
TABLE I
Position of Planets for the Beginning of kaliyuga
In this Table are given the positions of the planets, includ-
ing the Moon's apogee and ascending node, for the beginning of
Kaliyuga. The calculations of Brahmagupta are different from
those of the Sūryasiddhānta and of Āryabhaṭa I,
