Biography of great Indian mathematician in 250 words please guys please
Answers
Early life
Aryabhata was one of the first Indian mathematicians and astronomers belonging to the classical age. He was born in 476 BC in Tarenaga, a town in Bihar, India. It is however definite that he travelled to Kusumapara (modern day Patna) for studies and even resided there for some time. It is mentioned in a few places that Aryabhata was the head of the educational institute in Kusumapara. The University of Nalanda had an observatory in its premises so it is hypothesized that Aryabhata was the principal of the university as well. On the other hand some other commentaries mention that he belonged to Kerala.
Mathematical Work
Aryabhata wrote many mathematical and astronomical treatises. His chief work was the ‘Ayrabhatiya’ which was a compilation of mathematics and astronomy. The name of this treatise was not given to it by Aryabhata but by later commentators. A disciple by him called the ‘Bhaskara’ names it ‘Ashmakatanra’ meaning ‘treatise from the Ashmaka’. This treatise is also referred to as ‘Ayra-shatas-ashta’ which translates to ‘Aryabhata’s 108’. This is a very literal name because the treatise did in fact consist of 108 verses. It covers several branches of mathematics such as algebra, arithmetic, plane and spherical trigonometry. Also included in it are theories on continued fractions, sum of power series, sine tables and quadratic equations.
Aryabhata worked on the place value system using letters to signify numbers and stating qualities. He also came up with an approximation of pi ( ) and area of a triangle. He introduced the concept of sine in his work called ‘Ardha-jya’ which is translated as ‘half-chord’.
Astronomical Work
Aryabhata also did a considerable amount of work in astronomy. He knew that the earth is rotating on an axis around the sun and the moon rotated around it. He also discovered the position of nine planets and stated that these also revolved around the sun. He pointed out the eclipses; both lunar and solar. Aryabhata stated the correct number of days in a year that is 365. He was the first person to mention that the earth was not flat but in fact a spherical shape. He also gave the circumference and diameter of the earth and the radius of the orbits of 9 planets.

Answer:
Srinivasa Ramanujan is one of the world's greatest mathematicians, and he is known for his great work done in his field. He made many of his theories very popular in the world, and this is why his principles are still used in many countries.
He was born on December 22, 1887 in Erode, and he is known by many contributions made in the theory of numbers. It is very startling for many people, but in the beginning, Ramanujan never studied mathematics. He studied mathematics and became its expert in the latter part of his education.
He studied some books written by international mathematicians, and after a few years, he made many of his theories on mathematics.
He was very poor, and he did various research only under bad circumstances, but later he was supported by Ram Chandra Rao and his clerical job, due to which he was able to learn more and invent many new studies on mathematics.
In 1914, he won scholarship to England and studied hard under Godfrey. Not only did he work hard but also invented various other theories which made Hardy his fan. He surprised every teacher with the knowledge of mathematics because he never knew the modern techniques of mathematics, but at that time he still performed better than many professors and researchers.
He invented many theories, and the most famous ones are followed: Ramanujan continuously, Mok Live work, Ramanujan estimation, Ramanujan Pradhan, Ramanujan Live ceremony, Ramanujan's zodiac, Ramanujan's set series, etc. He also won the companionship of the royal society.
He worked for a very short period because he was only 32 years old, but his teachings are still alive in many people's minds and textbooks. So, this country was about Srinivasa Ramanujan, the country's best mathematician.
