Brahmagupta was an Indian mathematician who was born in Bhinmal, Rajasthan, around the year 598 AD. He lived most of his life at Bhinmal, King Vyaghramukha's capital. He was the director of the astronomical observatory at Ujjain, India's math capital, where he witnessed many brilliant mathematicians in action.
Contributions to Mathematics
The introduction of 'zero' to the number system, which stood for 'nothing,' was one of Brahmagupta's most famous contributions to mathematics. He provided various mathematical theories in the form of poetry in his book, 'Brahmasphutasiddhanta.' It incorporated a number of arithmetic principles that are still used in mathematical solutions today. 'A positive number multiplied by a negative number is negative.' 'A negative number multiplied by a positive number is negative.’
Theories like the 'Pythagorean Theorem' for a right-angle triangle and other geometrical principles are covered in the book. Brahmagupta was the first to calculate the area of a triangle and to develop essential trigonometric concepts like the sin function values. He was the one who first proposed the cyclic quadrilateral formula. To be precise, he specified the value of 'Pi' as square root ten, with 3 as the practical number. Negative numerals were also introduced by him.
Conclusion
According to Brahmagupta, the Earth and the cosmos are not flat but rather spherical. He was the first to utilise mathematics to forecast planet and eclipse placements. Even though all of this seems to be apparent and straightforward replies, it was a big scientific discovery at the time.
He also computed the duration of the solar year, which he estimated to be 365 days, 5 minutes, and 19 seconds, which is quite close to the current estimate of 365 days, 5 hours, and 19 seconds. 'Corpses fall towards the earth because it is in the nature of the soil to draw bodies, just as it is in the nature of water to flow,' he stated.
