Precise Determination of the Ascendant in the Lagnaprakarana - III

Authored by the celebrated mathematician-astronomer Madhava, the Lagnaprakarana is an important astronomical text dedicated to the determination of the udayalagna or the ascendant, and is notable for its technical brilliancy and multiple approaches to a given problem. In continuation of our previous papers on this text, here we discuss additional methods for precisely determining the udayalagna as described in the third chapter of the Lagnaprakarana. The procedure prescribed here makes use of two quantities knows as the sanku and the drggati.
