Biography of Abul Wafa

Muslim mathematicians phenomenal in the golden era of Islam was not only Al-Khwarizmi. In the 10th century AD, Islamic civilization has also been 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 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 good in mathematics, he was renowned as a famous engineer and astronomer of his day.

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

"Abul Wafa dalah greatest mathematician in the 10th century AD," said Kattani. Why not. Throughout his life, the employees have rendered science a series of important innovations gave birth to the science of mathematics. He noted Eucklid write a critique of thinking, and Al-Khawarizmisayang Diophantos treatise that has been lost. The ilmuwanpun bequeath Kitab Al-Us (Complete Book) which deals with 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 was also instrumental 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 of forming a sine table. He also confirmed the value of the sine of 30 degrees to the eighth desimel. More Why did gumkan again, Abul Wafa made a special study of ta for NGEN and compute a tangent table fruit.

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

Fruit of his thinking in mathematics is very influential in the Western world. In the 19 th 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 think pieces 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 June 10, 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 the Abu
Yahya al-Marudi and Abu al-Ala 'Ibn Karnib.

Abul Wafa grew up in the era of the rise of a new Islamic dynasty that ruled Iran. Dynasty which had ruled in the name of the region's Buwaih Persia - Iran and Iraq ñ in the year 945 to 1055 AD Buwaih Sultanate flag stuck in the period of transition of power from Arabic to Turkish. Dynasty which 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 the Baghdad government as Ad-Dawla Adud ruled from 949 to 983 M. Ad-Dawla Adud government is supporting and facilitating the scientists and artists.

Support is what makes Abul Wafa decided to move from his home to Baghdad. The scientists of Khurasan was 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.

Other mathematicians who also worked at the court ad-Dawla Adud among others, Al-and Al-Sijzi Quhi. In the year 983 AD, succession occurs in Buwaih Dynasty. Replaced ad-Dawla Adyd 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 have been mounting as he wanted to build an observatory. Abul Wafa and Al-Quhi his ambition was to realize the sulatan. Astronomical Obser vatorium was built in the park is tana sultan in Baghdad. Abul Wafa was hard work successfully. 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.

He wrote several valuable books, among others; Book fima Yahtaju Ilaihi al-Kuttab wa al-Ummal min 'Ilm al-reckoning a book on arithmetic. Two copies of the book, unfortunately incomplete, is now in the library of Leiden, the Netherlands 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 for a specific request from the Caliph Baha 'ad Dawla. The copies are in libraries Mosque Aya Sofya, Istanbul. Kitab al-Majesti book by Abul Wafa is the most famous of all the books he wrote. Copy of which has also been incomplete now stored in the Paris National Library, Pran cis.

Unfortunately, in her treatise on critical thinking dap MIDI Cable Euclid, Diophantus, and al-Khwarizmi was destroyed and lost. Indeed modern civilization owes to Abul Wafa. Results of the study and his works are inscribed in the book of a series of very significant influence to the development of science, especially trigonometry and astronomy.

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

Eternal Moon Crater

Abul Wafa was phenomenal. Even in the modern Muslim world is not too well known name, but his figure in the West it is very shiny. No wonder, if the Muslim scientist was 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 crater name to the moon gradually in the 20th century AD, between the years 1935, 1961, 1970 and 1976. Abul Wafa one.

Mostly, Muslim scientists in the crater of the moon diadadikan nicknamed the West. Abul Wafa was one scientist who was enshrined in the crater of the moon with the original name. Moon crater Abul Wafa is located at the coordinates of 1:00 Eastern, East 116.60. Abul Wafa moon crater diameter reaches 55 km in diameter. Crater depth of 2.8 km of the month.

Location of the moon crater Abul Wafa is located near the equator of the moon. Adjacent to the crater sepasangang Ctesibius and Heron on the east. In the southwest of the 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 recognize service and contribution as an astronomer at the X. century

Mathematics Ala Abul Wafa

One of the largest service provided Abul Wafa for the study of mathematics is no metri Trigo. Trigonometry comes from 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, though 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 is just a piece of the ideas of Abul Wafa which still survive. His ability to create new mathematical formulas to prove that Abul Wafa is a Muslim who is a genius mathematician.
