BHASKARACHARYA
THE GREAT
INDIAN MATHEMATICIAN
Bhaskaracharya (also
known as Bhaskara II) was a great Indian mathematician and an astronomer. He
was born in Karnataka (1114-1185). Bhaskaracharya learned mathematics from his
father Maheswara, a mathematic scholar. His main work is ‘Siddhanta Shiromani’,
which is divided into 4 parts. Lilavati, Bijaganita, Grahaganita and
Goladhyaya. His famous discovery is principles of differential calculus and its
application to astronomical problems and computations.

CONCLUSION
‘Bhaskara – the teacher’ was a great Indian mathematician. Bhaskara and
his works represent a significant contribution to mathematical and astronomical
knowledge in the 12th century. His works
are outstanding for its systemisation, improved methods and the new topics that
he has introduced.
