Question

When was Bhaskaracharya born?
A. 476 A.D.
B. 1114 A.D.
C. 598 A.D.
D. 770 A.D.

Answer 1

Hint: The great mathematician Bhaskaracharya was also known as Bhaskara II. As there was an Indian mathematician and astronomer named as Bhaskara I. Bhaskaracharya contributed to the mathematical and astronomical world in the 12th century.

Complete step-by-step answer:
As we all know about the great contribution of Bhaskaracharya in mathematics was in the 12th century . This simply means that Bhaskaracharya must borned in or before the 12th century.
He has a main interest in mathematical topics such as Algebra, Calculus, Arithmetic, Trigonometry etc.
He has been called the greatest mathematician of medieval India. He named some of his work as ‘Siddhanta – Siromani’ which consists of four main parts such as arithmetic, algebra, mathematics of planets and spheres.
The great mathematician Bhaskaracharya was born in a brahmani of Mahesvara in 1114 A.D. at Vijayapura, India. He died at the age of 71 in 1185 A.D. at Ujjain, INDIA. At the time of death Bhaskaracharya was in Ujjain as head of an astronomical observatory which was a leading mathematical centre in India at that time.
 He understands negative numbers and zero and that is why he had given the formula of \[{x^2}\]as \[\sqrt {a \pm \sqrt b } = \sqrt {\dfrac{{a + \sqrt {{a^2}} - b}}{2}} \pm \sqrt {\dfrac{{a - \sqrt {{a^2} - b} }}{2}} \]. He had many such great works in mathematics which is now used in studies of students and mathematicians and will go on in use in future too.
Hence B is the correct option.

Note:- A.D. is known as Anno Domini which is used to label or number years. The era is based on traditionally reckoned year of conception so the A.D. in the birth year of Bhaskaracharya ( i.e. 1114 A.D. ) is just a way of labelling the year.
