Muslim mathematicians phenomenal in the golden era of Islam was not just Al-Khwarizmi. In the 10th century AD, Islamic civilization also had a great mathematician who is not less than Khwarizmi. Muslim mathematician whose name is somewhat less familiar sounding name was Abul Wafa Al-Buzjani. "He is one of the greatest mathematicians who owned the Islamic civilization," said Mr. History of Science, George Sarton in his book titled Introduction to the History of Science.


Abul Wafa was a versatile scientist. In addition to candidate in the field of mathematics, he was renowned as a famous engineer and astronomer of his day.

Gait and his thinking in science recognized Western civilization. In recognition of his services to develop the world of astronomy, astronomy world organization perpetuate his be named one crater month. In the field of mathematics, Abul Wafa also contributed much that is essential for the development of numerology.

"Abul Wafa is greatest mathematician in the 10th century AD," said Kattani. Why not. Throughout her life, the science of employees have rendered a series of important innovations gave birth to the science of mathematics. He was recorded to write a critique of thinking Eucklid, and Al-Khawarizmisayang Diophantos treatise has been lost. The scientists also bequeath Kitab-Us (Complete Book) that discusses the science of arithmetic (arithmetic) practical. Other contributions are not less important in the mathematical sciences is the Book of Al-Handasa which examines the application of geometry. He also made a large contribution in developing trigonometry.

Abul Wafa was recorded as the first mathematician who sparked the general formula of the genus. In addition, the mice were ma mate sparked a new method to form a sine table. He also confirmed the value of the sine of 30 degrees to desimel eighth place. More menga gumkan again, Abul Wafa had made a special study of ta missed and compute a tangent tables.

If you ever studied mathematics would never know the term co secant and secant. Apparently, Abul Wafalah who first introduced the term math is very important. Abu Wafa was known to be a genius in the bi dang geometry. He was able to nyelasikan the geometry issues are very tang with cash.

Fruit of his thinking in mathematics is very influential in the Western world. In the 19th century AD, Baron Carra de Vaux to take the concept of secant triggered Abul Wafa. Unfortunately, in the Islamic world actually his name is rarely heard. Almost never, Islamic civilization history lessons taught in the country and introduced the world to review and fruit thought Abul Wafa. It is ironic.

Indeed, it's versatile scientist named Abu al-Wafa Muhammad Ibn Muhammad Ibn Yahya Ibn Ismail Ibn 'Abbas al-Buzjani. He was born in Buzjan, Khurasan (Iran) on 10 June 940 / 328 H. He learned mathematics from his uncle named Abu Omar al-Maghazli and Abu Abdullah Muhammad Ibn Ataba. Meanwhile, the science of geometry known from Abu
Yahya al-Marudi and Abu al-Ala 'Ibn Karnib.

Abul Wafa grew up in the era of the rise of a new ruling Islamic dynasty in Iranian territory. Dynasty which was the name that came to power in the region Buwaih Persia - Iran and Iraq ñ in the year 945 to 1055 AD Buwaih Sultanate flag stuck in between the period of transition of power from Arabic to Turkish. Dynasty that originated from the Turkish tribes were able to overthrow the rule of the Abbasid dynasty centered in Baghdad at the time of Ahmad Buyeh leadership.

Buwaih Dynasty moved the capital to Baghdad when his government Adud Ad-Dawla reigned from 949 until 983 AD Ad-Dawla Adud Government strongly supports and facilitates the scientists and artists.

Support is what makes Abul Wafa decided to move from his home to Baghdad. The scientists of this Khurasan then decided to dedicate himself to science in the court of ad-Dawla Adud in the year 959 AD Abul Wafa not the only mathematician who devoted himself to science at the palace.

Another mathematician who also worked at the palace Adud ad-Dawla, among others, Al-and Al-Sijzi Quhi. In the year 983 AD, the succession of leadership occurred in Buwaih Dynasty. Adyd ad-Dawla replaced his son named Sharaf ad-Dawla. Just like his father, the new sultan was also strongly supports the development of mathematics and astronomy. Abul Wafa was more comfortable working in the palace.

Love of the sultan in astronomy rapidly escalated when he wants to build an observatory. Abul Wafa and his friend Al-Quhi sulatan even realize his ambition. Obser vatorium astronomy was built in the park is tana sultan in Baghdad. Abul Wafa hard work was successful. The observatory was officially opened in June 988 AD

To monitor the stars from the observatory, in particular Abul Wafa build a wall quadrant. Unfortunately, the observatory did not last long. Once Sultan Sharaf ad-Dawla's death, the observatory was then closed. A series of major works have been produced during Abul Wafa dedicated himself in the palace of the sultan Buwaih.

Some valuable books which he wrote, among others; Book fima Yahtaju Ilaihi al-Kuttab wa al-Ummal min 'Ilm al-hisab a book on arithmetic. Two copies of the book, unfortunately incomplete, now in the library of Leiden, Holland and Cairo Egypt. He also wrote "Kitab al-Kamil".

In geometry, he wrote "The Book of fima Yahtaj Ilaih as-Suna 'fi' Amal al-Handasa". The book was written upon special request of the Caliph Baha 'ad Dawla. The copies are in libraries Aya Sofya Mosque, Istanbul. Kitab al-Majesti book by Abul Wafa is the most famous of all the books he wrote. The copies are also incomplete now stored in the national library of Paris, France cis.

Unfortunately, in her treatise on criticism against thought Euclid, Diophantus, and al-Khwarizmi was destroyed and lost. Indeed modern civilization owes to Abul Wafa. The results of research and work which is inscribed in a series of books giving a very significant influence to the development of science, especially trigonometry and astronomy.

The greatest mathematician in the 10th century it was closed on July 15 aged 998 in Baghdad, Iraq. However, the work and his thinking is still alive.


Eternal Moon Crater

Abul Wafa was phenomenal. Although in the modern Islamic world his name is not too well known, but his figure in the West it is very shiny. No wonder, if the Muslim scientists were so honored and respected. Western people still call it by name Abul Wafa. To honor the devotion and dedication in developing astronomical name was immortalized in the crater of the moon.

Among a series of Muslim scholars and scientists who owned the Islamic civilization, only 24 characters are immortalized in the crater of the moon and has received recognition from the International Astronomical Organization (IAU). To-24 officially recognized Muslim leader IAU as the name of the moon craters gradually in the 20th century AD, between the years 1935, 1961, 1970 and 1976. one of which Abul Wafa.

Most, Muslim scientists in the crater of the moon diadadikan with western nicknames. Abul Wafa was one scientist who is enshrined in the crater of the moon with the original name. Abul Wafa moon crater is located at the coordinates of 1:00 Eastern, East 116.60. Diameter crater Abul Wafa month reached 55 km in diameter. The depth of the crater that month reaches 2.8 km.

Location of the moon crater Abul Wafa is located near the equator of the moon. Located adjacent to the crater sepasangang Ctesibius and Heron on the east. In the southwest crater Abul Wafa months and there is a crater Vesalius in the northeast there is a larger moon crater named King. That world of modern astronomy recognizes service and contribution as an astronomer in century X.


Mathematics Ala Abul Wafa

One of the greatest services provided Abul Wafa for the study of mathematics is no metri Trigo. Trigonometry comes from the word trigonon = three angles and metro = measure. This is is a branch of mathematics dealing with angles and triangular Trigo no met rik functions such as sine, cosine, and tangent.

Trig has a relationship with the geometry, although there is disagreement about what to do; for some, trigonometry is a part of geometry. In trigonometry, Abul Wafa has introduced the tangent function and improve the methods of calculating trigonometry tables. He also said to solve a number of issues relating to spherical triangles.

In particular, Abul Wafa successfully prepared formula into trigonometric identities. This is the formula that generates it:

sin (a + b) = sin (a) cos (b) + cos (a) sin (b)
cos (2a) = 1 - 2sin2 (a)
sin (2a) = 2sin (a) cos (a)

In addition, Abul Wafa also managed to establish a formula for parabolic geometries, namely:
x4 = a and x4 + ax3 = b.
Important formulas it is just a piece of the ideas of Abul Wafa which still survive. His ability to create new mathematical formulas to prove that Muslim Abul Wafa is a very genius mathematician.
