Abstract
Accuracy of the rule is discussed and comparison with the actual values of sine is made and also depicted in a diagram. In addition to the two proofs given earlier by M. G. Inamdar (The Mathematics Student, Vol. XVIII, 1950, p. 10) and K. S. Shukla, three more derivations are included by the present author.
Indian Journal of History of Science, Vol. 2, No. 2. (1967) pp. 121–136.
