The Astronomical Observatories of Jai Singh c15.s1.t4.8

c15.s1.t4.8

The radius(r) is supposed to be divided into 3438 equal parts, which are, as a matter of convenience, termed minutes, and the sines, etc. (bhujajyā, kotijyā, chala karna, etc.), are expressed in terms of this radius (see my Indian Mathematics, p. 11).
