Srinivasa Ramanujan was a renowned Indian mathematician born in 1887 in Tamil Nadu, India. He made extraordinary contributions to mathematical analysis, number theory, infinite series, and continued fractions. Some of his key achievements include formulating the Ramanujan prime, the Ramanujan theta function, and discovering the Ramanujan constant and the Rogers-Ramanujan identities. Despite facing challenges with his education due to poverty, he was a self-taught mathematician and gained recognition after his letter containing his original research and results was received by Professor G.H. Hardy of Trinity College, Cambridge University. Ramanujan worked extensively on elliptic functions, continued fractions, infinite series, and solving cubic and quartic equations

5. He worked on…
1- Elliptic Functions:
2- F(z) and f(w/z) is same thing.
3- Continued fraction:
4- Infinite series
5- In 1900, he workes on his own math summing geometric and
arithmetic series.

6. 6-He solved cubic equations. (1902)
ax3+bx3+cx+d=0
7-He went on finding his own method of solving quantic
equation.
ax4+bx3+cx2+dx+e=0
8- He also investigated the series (1/n) and calculated constant
into 15 decimal places.
9- He began to study the Bernoulli’s (it was his own
independent discovery)
(Bernoulli equation) x/(ex-1)=(bnxn)/n
10- He also worked on hyper geometric series.
11- He also, Investigated the relation between series and
integrals.
