Question

Biography of Aryabhatta

Answer 1

Answer:ryabhata was an acclaimed mathematician-astronomer. He was born in Kusumapura (present day Patna) in Bihar, India. His contribution to mathematics, science and astronomy is immense, and yet he has not been accorded the recognition in the world history of science. At the age of 24, he wrote his famed “Aryabhatiya”. He was aware of the concept of zero, as well as the use of large numbers up to 1018. He was the first to calculate the value for ‘pi’ accurately to the fourth decimal point. He devised the formula for calculating areas of triangles and circles. He calculated the circumference of the earth as 62,832 miles, which is an excellent approximation, and suggested that the apparent rotation of the heavens was due to the axial rotation of the earth on its axis. He was the first known astronomer to devise a continuous counting of solar days, designating each day with a number. He asserted that the planets shine due to the reflection of sunlight, and that the eclipses occur due to the shadows of moon and earth. His observations discount the “flat earth” concept, and lay the foundation for the belief that earth and other planets orbit the sun.

Answer 2

ARYABHATA(476—550AD)

(1) Aryabhatta was born in 476 A.D. Kusumpur, India.He was the first in the line of great

mathematicians from the classical age of Indian Mathematics and Astronomy.

(2) His famous work are the” Aryabhatiya “and the”Arya‐siddhanta”.The Mathematical

part of the Aryabhatiya covers arithmetic. algebra, plane and spherical trigonometry.The

Arya‐siddhanta, a lot work on astronomical computation.

(3) Approximation of Pi: Aryabhata work on the approximation for pi (π) and may have

come to the conclusion that π is an irrational number.In the 2nd part of Aryabhatiya, he

writes the ratio of circumference to diameter is 3.1416.

(4) Aryabhata given the formula for area of a triangle .

(5) He was first person to say that Earth is spherical and it revolves around the sun.

(6) He gave the formula (a+b)2 =a2 + b2 + 2ab.
