The bhujājyā and koṭijyā of the difference between the longitudes of the Sun and the Moon is multiplied by half of the koṭijyā of the difference between the longitudes of the Sun and the mandocca of the Moon and divided by the trijyā. Of these two, the one obtained from the koṭijyā is applied to 10 times the hypotenuse of the Moon in minutes, positively or negatively depending on whether the ayanas are the same or different. The square root of the sum of the squares of that and the bāhuphala is the distance of separation between the Moon and the Earth (in yojanas).
