Dyujyā (द्युज्या) refers to the “day-radius”, according to verse 21 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 square-root taken from—the square of the Rsine [of the Sun’s longitude] decreased by the square of [the Rsine of] the declination corresponding to the longitude—is the koṭi of this [declination] itself. Or, the last day-radius multiplied by the Rsine [of the Sun’s longitude] and divided by the radius is the koṭi corresponding to this declination. Here, [scholars] state the square root taken from—its square increased by the square of the Rcosine [of the Sun’s longitude]—to be the day-radius. The koṭi of the desired declination multiplied by the maximum ascensional difference and divided by the day-radius (dyujyā) is the Rsine of the ascensional difference”.

context information

Sanskrit, also spelled संस्कृतम् (saṃskṛtam), is an ancient language of India commonly seen as the grandmother of the Indo-European language family (even English!). Closely allied with Prakrit and Pali, Sanskrit is more exhaustive in both grammar and terms and has the most extensive collection of literature in the world, greatly surpassing its sister-languages Greek and Latin.
