# Five famous mathematicians of ancient India-

The contribution of Indian mathematicians to the people of the world is everlasting. According to historical Vatham, mathematics gained an extraordinary status in the Gupta period. In ancient Sutra literature, there are methods of discussion and measurement of circles, semicircles, triangles, quadrilaterals, etc. for the construction of altars in the customs. From this, the knowledge of the geometry of the ancient Indian Aryans is found. In ancient times, mathematics and algebra were discussed as part of Vedanga called Jyotisha and were published in the form of formulas. In ancient Greek mathematics, there were no more than ten thousand names, but it was the ancient Indian mathematicians who invented the first zero and decimal numbers in the world. These two inventions are among the best in the world of mathematics. This makes it possible to express happy numbers in a single decade. All this knowledge from the Hindus spread to Europe through the Arabs.

Today we will learn about those five famous mathematicians.

1.Aryabhata

Aryabhata was the first notable mathematician of ancient India. He appeared in the Gupta period in a village called Kusumpur near Patna, probably in 48 AD. He was the first to discover and reveal that the earth revolves around the sun in his book Aryavattiya, written long before Galileo. He was the first to point out the real cause of lunar eclipses and solar eclipses. His unique discovery is the discovery of zero. In the third chapter of the Aryabhatiya text, he mentions various sources of mathematics. Aryabhata I was not only an astronomer of ancient India but also one of the best mathematicians. In the case of pure mathematics, he studied arithmetic and other mathematics, Discussed Arts Department, Field Department, and Sphere. His pure mathematics deals with square root, cubic root, parallel class sum, solution of quadratic equations. According to many, he is the first to determine the ratio of the circumference of a circle to its diameter. He invented a fancy method of expressing numbers by letters.

2.Brahmagupta –

The famous algebraic and astronomer of ancient India, Brahmagupta was born in 598 AD in the province of Multan. His book Brahmagupta Siddhanta is world-famous. In this book, he discusses astrology, arithmetic, and algebra. In the arithmetic part of the book, his contribution in the field of progress, parts, divisions, symmetrical fields, and in the field of pure mathematics deserves special praise.

3.Mahaviracharya –

Researchers believe that Mahaviracharya of the sixth-seventh centuries AD was a mathematician of the later period of Mahabiracharya Brahmagupta. His famous mathematics book "Collection of Mathematics". This book discusses

arithmetic, geometry, and dimension in 9 chapters. Now that we can divide a number by a fraction, we multiply the fraction upside down, He wrote that rule in his book in a beautiful way and multiplied the divisible by it.

4.Sridharacharya –

The famous philosopher and lyricist Sridharacharya was probably born in 991 AD in the Hughli district. The name of his mathematics book is 'Ganitsar'. This book is composed of three hundred verses. So its other name is Trishatak Number Counting, Normal Number, Multiplication, Division, Zero, Measurement, Square, Cube, Fraction, Triad, Interest, Collective Delivery, and Moderation. He was the first to distinguish algebra from arithmetic. A detailed discussion of zero is a notable feature of the book. He says that adding or subtracting zero with a number is the sum and subtraction of that number. However, if you multiply a number by zero, the product is zero.

The famous mathematician and astronomer Bhaskaracharya of ancient India were probably born in 1114 AD in the village of Bidar in the Deccan. The name of the famous book of Bhaskaracharya is "Siddhanta Shiromani". The book is divided into four chapters. 1.Lilabati or Algebra, 3.Granthaganitadhyaya, 4. Goladhya Bhaskaracharya's outstanding daughter "Lilabati", wrote the first chapter of the book "Siddhanta Shiromani" and hence the name Lilabati is named after her. Lilavati says that Pati means order or method and the part of mathematics which deals with addition, subtraction, multiplication, and division method is called arithmetic. Bhaskaracharya says that dividing a number by zero makes the quotient infinite. He said as an example that 3/0 is a fraction whose denominator is zero, it is an infinite quantity. He independently discovered the seeds of what is now called calculus in Western mathematics. But no ancient Indian mathematician after him has been able to follow or develop that subtle method.       In mathematics and hemisphere, Bhaskaracharya describes the method of determining the surface area of ​​a sphere, determining the longitude of the moon, the spherical shape of the earth, and the gravitational force of the earth.
