A reconstruction of Smogulecki and Xue's table of trigonometrical logarithms (ca. 1653)

Abstract

Smogulecki and Xue constructed the first Chinese table of trigonometrical logarithms around 1653. The table gave the logarithms of the sines, cosines, tangents and cotangent from 0 to 45 degrees, for every hundredth of a degree. It is reconstructed here.
