Were Nasir al-Din al-Tusi and Al-Ghazali both mathematicians?
Nasir al-Din al-Tusi Muhammad ibn Muhammad ibn al-Hassan al-Tūsī (Persian: محمد بن محمد بن الحسن الطوسی‎ ‎ ; 18 February 1201 – 26 June 1274), better known as Nasir al-Din Tusi (Persian: نصیر الدین طوسی‎ ‎ ; or simply Tusi in the West), was a Persian polymath, architect, philosopher, physician, scientist, and theologian.
Abu al-Wafa' Buzjani Abū al-Wafāʾ, Muḥammad ibn Muḥammad ibn Yaḥyā ibn Ismāʿīl ibn al-ʿAbbās al-Būzjānī or Abū al-Wafā Būzhjānī (Persian: ابوالوفا بوزجانی or بوژگانی‎ ‎ ) (10 June 940 – 15 July 998) was a Persian mathematician and astronomer who worked in Baghdad. He made important innovations in spherical trigonometry, and his work on arithmetics for businessmen contains the first instance of using negative numbers in a medieval Islamic text.
