It has been demonstrated in detail that Indian mathematics employed, in its search for better results, improved rules of interpolation, by using the second differences and that a particular case, upto the second order, of the more general Newton-Stirling interpolation formula was known to Brahmagupta (*c* A.D. 625).³ Following this line of thought, the Kerala astronomer Govindasvāmin (*c*. 800-850) has enunciated a set of rules for the computation of intermediary functional values, different formulae being laid down for different augmental intervals:
