Aryabhata II.
Aryabhata II was an Indian mathematician and astronomer who probably lived in the 10th century. He is known for his major astronomical work Maha Siddhanta.
Almost nothing is known about him and his life dates are uncertain. According to Pingree, it can be classified from 950 to 1100. Most of his major astronomical work Maha Siddhanta is dated to around 950. The key dates come from the fact that Bhaskara II. (12th century) refers to him and Aryabhata II. Again refers to Sridhara (around 870-around 930).
It is usually called Aryabatha II to distinguish it from the older Aryabhata (Aryabatha I).
The first 12 chapters (of 18) of the Maha Siddhanta deal with theoretical astronomy (planetary locations, solar and lunar eclipses, conjunctions of planets, moonrise and rising and setting of planets), the last six chapters (13-18) deal with geometry, geography and Algebra with astronomical applications and have the main title About the Sphere (Goladhyaya). The work is written in Sanskrit verse. This includes a method to determine the cube root (which was already known to the older Aryabhata I) and sine tables.
The Maha Siddhanta was published in Sanskrit by Sudhakara Dvivedi in 1910 (Benares Sanskrit Series, with commentary in Sanskrit).
