Thriraasijeevaa valanajyakaa hruthaa sileemukhai

rankulathaam vrajanthi thaa: dvisankunaa drushtigathi:

saraachalairvibhaajithaa lambana naadikaa phalam

  Radius and the valanajya when divided by 5, are converted into angulas. The R sine of driggati multiplied by 2 and divided by 75 gives ghatika of the parallax in longitude. (Sishyadhi vruddhi Tantra 13-11)]]>
