Several methods for deductions of the rule given in the *Sūryasiddhānta* and *Āryabhaṭīya* have been worked out by Delambre¹, Burgess², Singh³, Naraharayya⁴ and Ayyanger⁵. The methods given by last two scholars are reproduced by Srinivasiengar⁶. In a few cases, values given in the *Jyā* (Indian sine) table derived from the rule of the *Sūryasiddhānta* do not strictly agree with the modern values. To remove the deviation, Srinivasiengar formulated certain subsidiary rules¹.
