Column A is taken from the table of differences given in the Gitika 
quoted above, and is identical with the table given in the Surya eet 
Colamn B is obtained from Ptolemy’s table of chords by multiplying by 
“ATT45 (-5 3 a): Column C is obtained from the Paichasiddhantika by 

3 : 2 
iplyi * ox .e.. the value of 7m attributed 
multiplying by °4775 ( Svwisie) using es 
to Aryabhata. If Ptolemy’s value had been used in this case also, the agree- 
ment with column B would have been closer.
