Coba jelasin 'Abd al-Hamid ibn Turk dari Matematik pada zaman pertengahan Islam dalam bahasa melayu dong

'Abd al-Hamid ibn Turk contributed to the study of quadratic equations.

Arab mathematician and geometer Thabit ibn Qurra (b. 836) made many contributions to mathematics, particularly geometry. In his work on number theory, he discovered an important theorem which allowed pairs of amicable numbers to be found, that is two numbers such that each is the sum of the proper divisors of the other. Amicable numbers later played a large role in Islamic mathematics.

Astronomy, time-keeping and geography provided other motivations for geometrical and trigonometrical research. Thabit ibn Qurra studied curves required in the construction of sundials. Thabit ibn Qurra also undertook both theoretical and observational work in astronomy.
