vs. 17] A rule relating to the determination of the magnitude and direc tion of the (90710-0alam0 17. The Rsine of the declimation calculated from the Rversed sine of the kott of the tropical (sy0 ) longitude of the Sun or Moon1 for that time (i.e., for the beginning, middle, or end of the eclipse) (is the Rsine of the 4y270-0ala70). In the eastern half of the disc (of the Sun or Moon), the direction (of the guru0 ula710) is the same as that of the para0* (of the Sun or Moon) In the western half, the direction is contrary to that of the gyna. If ). be the tropical longitude of the eclipsed body, then its k0t is 2 -) , 2.-90, 270"-५, or ).-270", according as the clipsed body is in st second, third, or fourth quadrant 69 If denote the 501 of the tropical longitude of the eclipsed body, then, according to the above rule where e is the obliguity of the ecliptic. Rsin (gyan0-0al474) == This formula is equivalent to that given by the author in the Malta-Bhas karya, where I has been replaced by the bhaja of .+90-.* For the bluja of .-+-90° is equal to 90°-).,2-909, 270°-*, or ).-270", according as the eclip sed body is in the first, second, third, or fourth quadrant. Correct. As pointed out by me in the Mala-Bhaskarya, the above formula is in 1 The Sun is taken when the eclipse is solar, and the Moon is taken when the eclipse is lumar.
- 4jyana means “the northerly or southerly course (of a planet)”. The
course (yana) is north or south according as the planet lies in the half orbit beginning with the tropical sign Carpricorn or in that beginning with the tr० pical sign Cancer
- In my note to MBh, v. 45, Rversi0 (.+90°) stands as usual for Rversin
{tlja (.+-90")} w. 45, notc.
