Abstract

This article examines Al-Kāshī's Khāqānī sine table in Miftāḥ al-Ḥisab, converting it from the sexagesimal to decimal system. Our investigation includes a comparative analysis with a modern sine table to evaluate the accuracy of the Khāqānī sine values. Additionally, we address a copyist error in the table, providing corrections and subsequently restoring the table.
