## How many formulas did Ramanujan give independently on mathematics?

It contained 120 formulas among which he identified one for knowing how many prime numbers there are between 1 and a certain number, and others that allowed one to calculate quickly the infinite decimals of the number pi.

### What is Ramanujan equation?

In mathematics, in the field of number theory, the Ramanujan–Nagell equation is an equation between a square number and a number that is seven less than a power of two. It is an example of an exponential Diophantine equation, an equation to be solved in integers where one of the variables appears as an exponent.

What did Ramanujan invented in maths?

He worked out the Riemann series, the elliptic integrals, hypergeometric series, the functional equations of the zeta function, and his own theory of divergent series, in which he found a value for the sum of such series using a technique he invented that came to be called Ramanujan summation.

Was Ramanujan attacked?

They did not consider the emotional and social sacrifices that Ramanujan had made by crossing the seas. In the hollow streets of Cambridge, he was beaten and bullied by British soldiers who resented the fact that he continued to study while they fought in the war.

## What are Ramanujan numbers?

1729, the Hardy-Ramanujan Number, is the smallest number which can be expressed as the sum of two different cubes in two different ways. 1729 is the sum of the cubes of 10 and 9 – cube of 10 is 1000 and cube of 9 is 729; adding the two numbers results in 1729.

### How old was Ramanujan when he started studying math?

Born in 1887 in a small village around 400 km from Madras (now Chennai), Ramanujan developed a passion for mathematics at a young age, but had to pursue it mostly alone and in poverty. Until, in 1913, he decided to write a letter to the famous Cambridge number theorist G.H. Hardy.

Are there any crazy formulas in Ramanujan’s work?

I would like to share a story I have heard about Ramanujan and yes it is enough crazy to share here. Once Ramanujan was admitted to hospital, he was sick. His mentor and a great mathematician Mr. Hardy went to see him. Mr. Hardy said, ‘The number of the taxi I came by is 1729 how uncool number is that!’.

Who was Srinivasa Ramanujan and what did he do?

Srinivasa Ramanujan (1887-1920) was an Indian mathematician who made great and original contributions to many mathematical fields, including complex analysis, number theory, infinite series, and continued fractions.

## Who is c.p.ramanujam and what did he do?

C. P. Ramanujam. Chakravarthi Padmanabhan Ramanujam (9 January 1938 – 27 October 1974) was an Indian mathematician who worked in the fields of number theory and algebraic geometry. He was elected a fellow of the Indian Academy of Sciences in 1973.
