In this paper, we study ghiyath al-din jamshid al-kashi’s (1380-1429 a.d.) main mathematical achievements. we discuss his al-risala al-muhitiyya (the treatise on the circumference), risala al-watar wa’l-jaib (the treatise on the chord and sine), and miftah al-hisab (the key of arithmetic). in particular, we look at al-kashi’s fundamental theorem, his calculation of π, and his calculation of sin1°.
