8 CONTENTS, For a maximum or minimum, di P must be ėqual to zero. di A But from the equation (I), we get 器魯 . cos t:၃n w, when the radius is unity. Substituting this value of we obtain Sin A cos?D sin w p cos A. -- Sin D. cos A =as 0. .". Sin A coso D Sin w as sin D coso A. or Sin D cos2D Sinow = Sin Docos? A. or Sin D ( cos?ID Sinow - coso A ) = 0. or Sin D (Sinow - SinoD. Sinow - 1 + SinoA)= 0 or Sin D (Sinow-SinoD Sinow-I + SinoD Sinow) - 0 or Sin D ( Sinow— I ) = 0; ". Sin D = 0. d A . a dD5° "n the equation (2 ), Hence, the motion of the Ayanagrha will be a maximum and in the positive direction at the first point of aries, when the Sine of the longitude of the Ayariagraha is zero. The maximum value - W. d D.I.397X 173". 447 ...' 3438 7o'. 4. When the longitude of the Ayanagraha is 9o, the precession will be 24; and at that instant, the annual motion of the Ayanagraha will be nothing a fact which demands the careful consideration of scholars. Slokas 14-19 show how to find out the true position of the sun by the application of the corrections known as mandabhalla, chara etc. Slokas 20-26 give the methods of finding out the mandabhala of the moon and other planets, and the Sighvabhala of the Mars and other planets, by the knowledge of their distance from the earth's centre.
