Question

State a contribution of Aryabhata and Bhaskara I to the development of trigonometry.

Answer 1

$\large{\bf{\blue{\underline{\underline{Hi....!! }}}}}$

#3 He made major contributions to Trigonometry and Algebra

For example in Ganitapadam his writings can be translated as “for a triangle, the result of a perpendicular with the half-side is the area.” In trigonometry, Aryabhatta gave a table of sines calculating the approximate values at intervals of 90°/24 = 3° 45′.

Answer 2

HE MADE MAJOR CONTRIBUTIONS TO TRIGONOMETRY AND ALGEBRA

✅️Aryabhatiya provides simple solutions to complex mathematical problems of the time like summing the first n integers, the squares of these integers and also their cubes. Furthermore, Aryabhatta correctly calculated the areas of a triangle and of a circle. For example in Ganitapadam his writings can be translated as “for a triangle, the result of a perpendicular with the half-side is the area.” In trigonometry, Aryabhatta gave a table of sines calculating the approximate values at intervals of 90°/24 = 3° 45′. In order to do this he used a formula for sin(n + 1)x – sin nx in terms of sin nx and sin (n – 1)x. He was also the one to introduce the versine (versin = 1 – cosine) into trigonometry.✅️
