Abstract

The paper discusses the trigonometrical series for π, sine, cosine and tan functions contained in the Karanapaddhati. The original texts and their translations are given. As to its date C. M. Whish attempted to fix it in the beginning of the eighteenth century. Whish's derivation is untenable and it is shown that the text is likely to be contemporaneous with, or even to antidate, the Tantrasamgraha, of Nilakantha Somasuttvan (A.D 1465-1545).
