A note on the sine table in ancient India

Abstract

In course of a correspondence with the author, Sri T. S. Kuppanna Sastry has drawn attention to the fact that the radius (trijya) used by Varahamihira in his Pancasiddhantika should be 120' and not 120' 1" which follows from the emended version of the text of Pancasiddhdntika, edited by Thibaut and Sudhakara¹. I have further looked into the matter and find that Thibaut and Sudliakara have made some wrong emendations in some portion of the original Sanskrit terms². Due to this emendation, some errors have crept in the results of jya-lengths given in my previous published paper.
