vs. 11] Therefore Similarly, Sun's parallax in longitude Moon's paralax in longitude ="(Moon's true daily motion in minutes०farc), minutes of 15x343४ 84 4(Sun's true daily motion in minutes), minutes of arc. 15x 3438 Therefore AT (Moon's true daily motion in minutes of arc 15x3438 -Sun's true daily motion in minutes of arc) 3438 x 4 79 The usual Hindu method for deriving this formula is to apply the follow ing proportion

  • When the dggatiya amounts to the radius (= 3488), the laाbora is

equal to 4 ghats; what them would be the value of the artbarma when the dgatjya has its calculated value?” The gha s of the lamba for the time of apparent conjunction having been thus determined, the time of apparent conjunction is obtained by using formula (2) above A rule relating to the determination of the 10t for the time of apparent conjunction af the Sun and Moon 11 . Multiply the Rsine of the d:ge#0 obtained by the method of successive approximation31 (i.e., multiply the Rsine of the dkkg2८ for the time of apparent conjunction) by the 1 While finding the nearest approximation to the lamburu for the time of apparent conjunction by the method of successive approximations, the Rsines of the dkksha obtained by the method of successive approximations is here meant the value of the Rsine of the dksha calculated at the last stage, which corresponds to the time of apparent conjunction.
