ربع مجيب Sine quadrant
rdfs:comment
كان الرُّبْع المُجَيَّب نوعًا من الربع استخدمه علماء الفلك في العصر الذهبي للحضارة الاسلامية. يمكن استخدام الأداة لقياس الزوايا السماوية، أو معرفة الوقت، أو ايجاد الاتجاهات، أو لتحديد المواقع الظاهرة لأي جرم سماوي في أي وقت. سميت هذه الأداة نسبة إلى دالة الجيب. اخترعها محمد بن موسى الخوارزمي في بغداد في القرن التاسع. The sine quadrant (Arabic: Rub‘ul mujayyab, الربع المجيب‎), sometimes known as the "sinecal quadrant", was a type of quadrant used by medieval Arabic astronomers. The instrument could be used to measure celestial angles, to tell time, to find directions, to perform trigonometric computations, or to determine the apparent positions of any celestial object for any time. The name is derived from the Arabic rub meaning 'a quarter' and mujayyab meaning 'marked with sine'. It was described by Muhammad ibn Mūsā al-Khwārizmī in 9th-century Baghdad, and was used throughout the medieval Islamic period to determine the proper times for Islamic prayer.

The name is derived from the Arabic rub meaning 'a quarter' and mujayyab meaning 'marked with sine'.
