Abu Al-Jud
Abū al-Jūd Muḥammad b. Aḥmad b. al-Layth was an Iranian mathematician who lived during 10th century and was a contemporary of al-Biruni. He used conics to solve quartic and cubic equations, a century before the more famous work of Omar Khayyam, although his solution did not deal with all the cases. Life Not much is known about his life. He seems to have lived in the east of Khurasan, within Samanid The Samanid Empire () was a Persianate society, Persianate Sunni Islam, Sunni Muslim empire, ruled by a dynasty of Iranian peoples, Iranian ''dehqan'' origin. The empire was centred in Greater Khorasan, Khorasan and Transoxiana, at its greatest ... territory. Sa'id al-Andalusi claimed that he lived in Valencia (Balansiya) and died in 1014 or 1015, but other sources didn't mention these information. It is likely that he became a scribe after acquiring basic knowledge on mathematics.

Iranian Peoples
Iranian peoples, or Iranic peoples, are the collective ethnolinguistic groups who are identified chiefly by their native usage of any of the Iranian languages, which are a branch of the Indo-Iranian languages within the Indo-European languages, Indo-European language family. The Proto-Iranian language, Proto-Iranians are believed to have emerged as a separate branch of the Indo-Iranians in Central Asia around the mid-2nd millennium BC. At their peak of expansion in the mid-1st millennium BC, the territory of the Iranian peoples stretched across the entire Eurasian Steppe; from the Danube, Danubian Plains in the west to the Ordos Plateau in the east and the Iranian Plateau in the south.: "From the first millennium b.c., we have abundant historical, archaeological and linguistic sources for the location of the territory inhabited by the Iranian peoples. In this period the territory of the northern Iranians, they being equestrian nomads, extended over the whole zone of the ste ...

Al-Biruni
Abu Rayhan Muhammad ibn Ahmad al-Biruni (; ; 973after 1050), known as al-Biruni, was a Khwarazmian Iranian scholar and polymath during the Islamic Golden Age. He has been called variously "Father of Comparative Religion", "Father of modern geodesy", Founder of Indology and the first anthropologist. Al-Biruni was well versed in physics, mathematics, astronomy, and natural sciences, and also distinguished himself as a historian, chronologist, and linguist. He studied almost all the sciences of his day and was rewarded abundantly for his tireless research in many fields of knowledge. Royalty and other powerful elements in society funded al-Biruni's research and sought him out with specific projects in mind. Influential in his own right, al-Biruni was himself influenced by the scholars of other nations, such as the Greeks, from whom he took inspiration when he turned to the study of philosophy. A gifted linguist, he was conversant in Khwarezmian, Persian, Arabic, and Sanskri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conic
A conic section, conic or a quadratic curve is a curve obtained from a cone's surface intersecting a plane. The three types of conic section are the hyperbola, the parabola, and the ellipse; the circle is a special case of the ellipse, though it was sometimes considered a fourth type. The ancient Greek mathematicians studied conic sections, culminating around 200 BC with Apollonius of Perga's systematic work on their properties. The conic sections in the Euclidean plane have various distinguishing properties, many of which can be used as alternative definitions. One such property defines a non-circular conic to be the set of those points whose distances to some particular point, called a ''focus'', and some particular line, called a ''directrix'', are in a fixed ratio, called the ''eccentricity''. The type of conic is determined by the value of the eccentricity. In analytic geometry, a conic may be defined as a plane algebraic curve of degree 2; that is, as the set o ...

Quartic Function
In algebra, a quartic function is a function (mathematics), function of the form :f(x)=ax^4+bx^3+cx^2+dx+e, where ''a'' is nonzero, which is defined by a polynomial of Degree of a polynomial, degree four, called a quartic polynomial. A ''quartic equation'', or equation of the fourth degree, is an equation that equates a quartic polynomial to zero, of the form :ax^4+bx^3+cx^2+dx+e=0 , where . The derivative of a quartic function is a cubic function. Sometimes the term biquadratic is used instead of ''quartic'', but, usually, biquadratic function refers to a quadratic function of a square (or, equivalently, to the function defined by a quartic polynomial without terms of odd degree), having the form :f(x)=ax^4+cx^2+e. Since a quartic function is defined by a polynomial of even degree, it has the same infinite limit when the argument goes to positive or negative infinity. If ''a'' is positive, then the function increases to positive infinity at both ends; and thus the function ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Omar Khayyam
Ghiyāth al-Dīn Abū al-Fatḥ ʿUmar ibn Ibrāhīm Nīshābūrī (18 May 1048 – 4 December 1131) (Persian language, Persian: غیاث الدین ابوالفتح عمر بن ابراهیم خیام نیشابورﻯ), commonly known as Omar Khayyam (), was a Persian poet and polymath, known for his contributions to Mathematics in medieval Islam, mathematics, Astronomy in the medieval Islamic world, astronomy, Iranian philosophy, philosophy, and Persian literature. He was born in Nishapur, Iran and lived during the Seljuk Empire, Seljuk era, around the time of the First Crusade. As a mathematician, he is most notable for his work on the classification and solution of cubic equations, where he provided a geometric formulation based on the intersection of conics. He also contributed to a deeper understanding of Euclid's parallel axiom. As an astronomer, he calculated the duration of the solar year with remarkable precision and accuracy, and designed the Jalali calendar, a solar ...

Khurasan
KhorasanDabeersiaghi, Commentary on Safarnâma-e Nâsir Khusraw, 6th Ed. Tehran, Zavvâr: 1375 (Solar Hijri Calendar) 235–236 (; , ) is a historical eastern region in the Iranian Plateau in West Asia, West and Central Asia that encompasses western and northern Afghanistan, northeastern Iran, the eastern halves of Turkmenistan and Uzbekistan, western Tajikistan, and portions of Kyrgyzstan and Kazakhstan. The extent of the region referred to as ''Khorasan'' varied over time. In its stricter historical sense, it comprised the present territories of Khorasan Province, northeastern Iran, parts of Afghanistan and southern parts of Central Asia, extending as far as the Amu Darya (Oxus) river. However, the name has often been used in a loose sense to include a wider region that included most of Transoxiana (encompassing Bukhara and Samarqand in present-day Uzbekistan), extended westward to the Caspian Sea, Caspian coast and to the Dasht-e Kavir southward to Sistan, and eastward to t ...

Samanid Empire
The Samanid Empire () was a Persianate Sunni Muslim empire, ruled by a dynasty of Iranian ''dehqan'' origin. The empire was centred in Khorasan and Transoxiana, at its greatest extent encompassing northeastern Iran and Central Asia, from 819 to 999. Four brothers— Nuh, Ahmad, Yahya, and Ilyas—founded the Samanid state. Each of them ruled territories under Abbasid suzerainty. In 892, Ismail Samani (892–907) united the Samanid state under one ruler, thus effectively putting an end to the feudal system used by the Samanids. It was also under him that the Samanids became independent of Abbasid authority. However, by 945, the government was under the de facto control of the Turkic military slave faction, and the Samanid family's authority had become purely symbolic. The Samanid Empire is part of the Iranian Intermezzo, which saw the creation of a Persianate culture and identity that brought Iranian speech and traditions into the fold of the Islamic world. This later co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sa'id Al-Andalusi
Ṣāʿid al-Andalusī (), in full Abū al-Qāsim Ṣāʿid ibn Abū al-Walīd Aḥmad ibn Abd al-Raḥmān ibn Muḥammad ibn Ṣāʿid ibn ʿUthmān al-Taghlibi al-Qūrtūbi () (1029July 6, 1070 AD; 4206 Shawwal, 462 AH), was an Arab qadi of Toledo in al-Andalus, who wrote on the history of science, philosophy and thought. He was a mathematician and scientist with a special interest in astronomy and compiled a famous biographic encyclopedia of science that quickly became popular in the empire and the Islamic East. Life Ṣāʿid al-Andalusī was born in Almería in al-Andalus during the Dhulnunid dynasty and died in Toledo. His Arab origins came from the tribe of Taghlib and his family had fled Cordova to take refuge in Almería during the civil war. His grandfather had been qadi (judge) of Sidonia and his father was qadi of Toledo until he died in 1057 when Ṣāʿid succeeded him.

10th-century Iranian Mathematicians
1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In mathematics The number 1 is the first natural number after 0. Each natural numbe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
