Source: INSA Digital Repository: Determination of Ascensional Difference in the LagnaprakaranaDorguṇa (दोर्गुण) refers to the “Rsine (of the Sun’s longitude)”, according to verse 20 of the Lagnaprakaraṇa (lit. “treatise for the computation of the ascendant), an astronomical work in eight chapters dealing with the determination of the ascendant (udayalagna or orient ecliptic point).—Accordingly, “The quotient of either the Rsine (dorguṇa) [of the Sun’s longitude] multiplied by [the Rsine of] the last (maximum) declination, or [the Rsine of] the declination corresponding to the desired longitude multiplied by the radius, divided by the Rcosine of the latitude, is the Rsine of the Sun’s amplitude. That [Rsine of the Sun’s amplitude] is the hypotenuse. [The Rsine of] the declination is the upright here, and indeed the earth-sine is the lateral”.
