Brahmagupta Formula
Brahmagupta discovered the formula for cyclic quadrilaterals, although it did not focus on the figure’s cyclic nature. Brahmagupta provided an approximate and exact formula for the area of any cyclic quadrilateral given the lengths of its sides.
Area = √(S – p)(S – q)(S – r)(S -s)
where,
- S = (p+q+r+s)/2
Brāhmasphuṭasiddhānta – Correctly Established Doctrine of Brahma
Of the many book that were written by Brahmagupta, Brāhmasphuṭasiddhānta written by him in 628 CE is the most prominent one. This book not only consists his astronomical work but a wide range of verses on mathematics are there too. A total of 1008 verse are there in this book. He also included various fundamentals of mathematics such as algebra, geometry, trigonometry and various algorithms in this book.
Although Brahmagupta believed as an astronomer who dabbled in mathematics, Brahmagupta is now best known for his contributions to mathematics. His works are source of inspiration for mathematicians and research scholars all around the world.
Who is Father of Arithmetic?
Arithmetic is one of the oldest and most fundamental branches of Mathematics, dealing with numbers and traditional operations such as addition, subtraction, multiplication, division, and so on. Arithmetic can be called the basics of number theory, dealing with numbers and finding out the relationship among numbers. It involves calculations among different numbers to obtain another number.
Let’s learn more about who described and explained arithmetic.
