Bhaskara II was also known by Bhaskaracharya, Bhaskara the teacher, and Bhaskara. The II was added to his name so there was no confusion between him and another 7th century mathematician and astronomer who was also named Bhaskara. He was born in 1114 in bijapur, karnataka which is possibly the bijjaragi of vijayapur.he died in 1185 at age 71, but during his life it’s said that he was the head of an astronomical observatory at ujjain which was the leading place in mathematics in ancient india. He lived in the sahyadri region of india. Most of his family were also scholars, his great great great grandfather was a court scholar, his father was an astronomer and a mathematician , which is where Bhaskara learned mathematics, it’s also assumed that Bhaskara’s daughter was good at mathematics because he mentions her and dedicates questions written in his work to her. Bhaskara’s son also assisted in setting up a school meant to focus on Bhaskara’s work in 1207.Achievements Bhaskara has been considered one of the greatest mathematicians of medieval india. His main work siddhanta shiromani (crown of treatises) has 4 part which is sometimes considered to be 4 seperate works because they each deal with different topics on arithmetic ,algebra, calculus astronomy and trigonometry. He completed the piece at age 36.The first part is lilavati. It was written in 1150 and it’s assumed that it was named after his daughter. There are stories that say Bhaskara predicted Lilavati would be childless and unmarried. To prevent this he predicted a perfect moment for the wedding to take place. He set up a cup with a hole at the bottom made to sink at the moment the wedding had to happen. He left the device in lilavati’s room and told her not to touch it, but she was curious. She leaned over the water and a pearl from her dress (or nose ring or necklace depending on whos telling the story) fell in and disrupted the water and the moment from the wedding went unnoticed much to the dismay of Lilavati and Bhaskara. Because lilavati was so heartbroken he promised to name his first work after her. There are 13 chapters in Lilavati, there are lots of definitions, arithmetic progressions and terms, geometric progressions , plane geometry, solid geometry, and the kuttaka which is an algorithm used to find integer solutions of linear diophantine equations in the form ax+by=c, the algorithm wasn’t created by bhaskara II it was invented by a mathematician aryabhatta. The work also includes a method to solve indeterminate equations and combinations, as well as the pythagorean theorem which is credited as to being proved by him. In lilavati there were also many different ways to calculate numbers including multiplication, progressions, and squares. Bhaskara used common objects in his examples like pearls and elephants so it could be easy for everyone to understand.
