Root extraction by Nizam al-Dīn al-Nīsābūrī (d. ca. 1330730AH)‎

الملخص EN

In this article, we discuss root extraction in al-Ḥasan al- Nīsābūrī (d.

Ca.

1330 AD), based on six copies of his manuscript titled<>.

Most of the studies we have consulted present al-Nīsābūrī as a religious scholar, an exegete of the Qur'an, and linguist, but they do not address his scientific production especially the mathematical one.

Hence, the benefit of this research is to initiate a new avenue in the study of the transfer of the mathematical results and concepts between different scientific foci in the Arab-Islamic civilization.

This research addresses the absence of studies dealing with some important aspects of overall mathematics produced in central Asia.

The importance of this study lies in the fact that it represents a link between what was produced in this field in the 13th century, by al-Țūsi(d.

1274) in his work <> and in the 15th century, by al-Kashi(d.

1429) in his treatise <>, in terms of tools and techniques.
