Indian Mathematicians and Astronomers

Bhaskara II, in his treatise 'Lilavati', explored the concept of 'infinite series' and developed methods for calculating sums of infinite series, contributing to the early development of calculus.

Brahmagupta, in his work 'Brahmasphuta Siddhanta', developed the 'Pell's equation' and provided a method for solving it, contributing to the field of number theory.

Srinivasa Ramanujan, who lived in the early 20th century, is regarded as one of the greatest Indian mathematicians, known for his remarkable contributions to number theory, mathematical analysis, and his discovery of various mathematical identities and formulas.

Baudhayana, an ancient Indian mathematician, is credited with developing the 'Pythagorean theorem' independently of Pythagoras, as evidenced in the 'Baudhayana Sulba Sutra'.

Aryabhata, in his work 'Aryabhatiya', developed trigonometric functions such as sine, cosine, and versine, contributing to the field of astronomy and trigonometry.

Aryabhata was a major figure in Indian astronomy. He lived in the 5th century CE and is known for his work on the heliocentric model of the solar system. Aryabhata also developed a number of mathematical techniques that are still used today.

Bhaskara II was a major figure in Indian astronomy. He lived in the 12th century CE and is known for his work on the heliocentric model of the solar system. Bhaskara II also developed a number of mathematical techniques that are still used today.

Brahmagupta, an Indian mathematician and astronomer, is credited with the formalization of the concept of zero in the 7th century AD.

Srinivasa Ramanujan was a self-taught Indian mathematician who made significant contributions to number theory, including the Hardy-Ramanujan asymptotic formula.

P.C. Mahalanobis developed the VED classification system, which is used to categorize inventory items based on their criticality.

C.R. Rao developed the ABC classification system, which is another method for categorizing inventory items based on their value and usage.

Varahamihira, an Indian mathematician and astronomer, developed the concept of the 'siddhantas', which were influential in astronomy and religious rituals.

Brahmagupta, an Indian mathematician and astronomer, developed the concept of the 'zero-divisor', which played a significant role in the development of algebra.

Bhaskara II, an Indian mathematician and astronomer, developed the concept of the 'chakravala method', which was used to solve indeterminate equations.

Aryabhata, an Indian mathematician and astronomer, developed the concept of the 'trigonometric functions', which were influential in astronomy and navigation.
