Contribution of Brahmagupta in Mathematics

What are the 6 Contributions of Brahmagupta in the field of Mathematics

Brahmagupta was one of the famous Indian mathematicians and astronomers. He was the first mathematician who described Zero and Negative Numbers. He was born in 598 CE in Bhinmal, the Indian state of Rajasthan. King Vyaghramukha was the ruler of Bhinmal and made Brahmagupta the head of the astronomical observatory in Ujjain. In those days,

Contribution of Brahmagupta in Mathematics

 1. Brahmagupta wrote many mathematical and astronomical textbooks while he was in Ujjain, including Durkeamynarda, Khandakhadyaka, Brahmasphutasiddhanta, and Cadamakela.

2. His significant contributions to astronomy are calculating the lunar and solar eclipses and predicting the position and motion of the planets. He calculated the length of the solar year down to the second as 365 days, 5 minutes, and 19 seconds.

3. Brahmagupta's most remarkable finding in geometry is his formula for cyclic quadrilaterals which is also known as Brahmagupta's formula. The cyclic quadrilateral refers to any four-sided figure whose corners touch the inside of a circle.  He found the value of ‘Pi’ .

4. Brahmagupta introduced zero as a number in its own right. Brahmasphutasiddhanta is the earliest known text that established rules for mathematical manipulation that applies to zero. 

5. Brahmagupta also introduced the concept of negative numbers. He established the basic mathematical rules for dealing with negative numbers in equations.

6. He also explained the ‘geometrical’ theories, similar to the ‘Pythagorean Theorem’. He also introduced the principles and rules of trigonometry and brought a guide to knowing the area of a triangle.
