It is longer in extent in the north-south direction, extending for just under 20 kilometers , and has a width about half that. The peak rises to an altitude of roughly 1.5 km, and there is a tiny, relatively fresh crater at the top.

He was a Sabian , a religious sect of Judeo-Christian origins from the 3rd century AD that worshipped the stars. His best-known achievement was the determination of the solar year as being 365 days, 5 hours, 46 minutes and 24 seconds. He produced a number of trigonometrical relationships: tan a = sin a / cos a sec a = (1+ tan a He also solved the equation sin x a cos x discovering the formula: sin x a a and used al-Marwazi 's idea of Tangents ("shadows") to develop equations for calculating tangents and cotangents, compiling tables of them. Al Battani worked in Syria , at ar-Raqqah and at Damascus , where he died. He was able to correct some of

Z entire Web this site Albategnius (Al-Battani, Muhammad ibn Jabir) (c. 850-929) An Arab prince, born in Batan, Mesopotamia, who was the leading astronomer and mathematician of his time. He drew up improved tables of the Sun and Moon, measured the eccentricity of Earth’s orbit and the inclination of Earth’s equator to its orbital plane, and derived an accurate length for the year, which was used in the Gregorian reform of the Julian calendar. His observations at Rakku, made over a 40-year period, were summarized in Movements of the Stars (first published in Europe in 1537) and enabled Hevelius to discover the secular variation in the Moon’s motion. In mathematics, Al-Battani introduced the use of signs. See also Arabian astronomy BACK TO TOP var site="s13space1234"
