Al- Battani was born in Battan , Harran , Syria in about 858 AD His family is Sabbian sect who performed the ritual worship of the stars. But he did not follow in the footsteps of his ancestors , he chose to embrace Islam . Interest with objects in the sky makes Al Battani then pursue astronomy . In informal education he received from his father who was also a scientist , Jabir Ibn al - Battani San'an . This belief strengthened by evidence of Al Battani ability to create and use a number of devices astronomical tools as did his father .
Moments later , he left Harran towards Raqqa located on the banks of the Euphrates , where he continued his studies . Here he conducted various studies until he found the brilliant discoveries . At that time , Raqqa become famous and achieve prosperity . This is because the caliphs Harun Al Rashid , the fifth Caliph of the Abbasid dynasty , on September 14, 786 to build a number of palaces in the city. It is an appreciation of a number of inventions produced by research conducted Al Battani . After the construction of a palace in Raqqa , the city became the center of activity both science and commerce is bustling . Results The thinking in the field of astronomy that receive worldwide recognition is the length of the earth around the earth . Based on his calculations , he declared that the earth revolves around the center of the solar system within 365 days , 5 hours , 46 minutes , and 24 seconds . The calculations are approaching the final calculations are considered to be more accurate .
That is the result of his efforts during 42 years of research initiated in young musa in Raqqa , Syria . He found that the longitude of the sun terajauh increased by 16.47 degrees since the calculation made by Ptolemy . This led to an important discovery about the curved motion of the sun . Al-Battani also determine accurately kemiringin ecliptic, the length of the season, and orbit the sun. He even managed to find the orbit of the moon and planets and establish a new theory to determine a condition of the possibility of sighting the new moon. This is connected with the turn of a month to the other.
Discoveries concerning curved lines moon and the sun, in 1749 and then used by Dunthorne to determine the motion acceleration month. In the field of mathematics, Al Battani also contributed brilliantly, especially in trigonometry. Like the, other Muslim scientists, he also wrote his knowledge in both areas it into a book.
His book on astronomy of the most famous is the Book of Al Zij. This book was translated into Latin in the 12th century under the title De Scienta Stellerum u De Numerical Stellerum et Motibus by Plato of Tivoli.

Al- Battani also find a number of trigonometric equations :
He also solves the equation sin x = a cos x and find the formula :
and using the notion of al - Marwazi about tangent to develop equations to calculate the tangent , cotangent and tangent calculation tabulated .
Other information contained in Fihrist also stated that Al Battani conducted research between the years 877 and 918. Not only that , in it also contained information regarding the end of life of the scientist 's . Fihrist stated that Al Battani died in a journey of Raqqa to Baghdad .
This trip is done as a form of protest because he taxed the excess . Al- Battani was reached Baghdad to submit complaints to the government . But then he breathed his last while on his way home from Baghdad to Raqqa
