Srinivasa Ramanujan, the man who knew infinity, have done some astounding discoveries during his early age. Ramanujan finds that the sum of all natural numbers is equal to -1/12. We know that if we add two or more positive integers we get a positive answer but Ramanujan discovered that 1+2+3+... = -1/12, it is difficult to believe this sum but ramanujan proved this by simple algebra. We call this sum as Ramanujan infinite sum, Ramanujan infinite summation, ramanujan infinite sum series, etc. I in this video have tried to explain you that how ramanujan proved the infinite sum formula which is very fascinating to watch. Ramanujan was a great mathematician, he did some astounding discoveries in the field of mathematics that reshaped the 20th century. In order to prove this infinite sum series we must learn about Grandi Series 1-1+1-1+.... and this infinite series 1-2+3-4+5-....... we learned in this video about how to find the sum of Ramanujan infinite series with the help of these two series. Ramanujan Summation is a technique invented by Srinivasa Ramanujan for assigning a value to a divergent infinite series. Ramanujan also has a huge impact on the foreign world as mathematician from all over the world wanted to meet him. Hollywood filmakers created Ramanujan movie that unfold the biography of Srinivasa Ramanujan, the man who knew infinity. #ramanujan, #ramanujansummation, #ramanujaninfinitesum, #ramanujansum #srinivasaramanujan, #ramanujanbiography #ramanujanhistory, #ramanujandiscoveries #ramanujansumproof, #themanwhoknewinfinity #ramanujanmovie ,#mathematics, #maths #infinity, #infiniteseries ramanujan movie | Ramanujan | ramanujan maths tricks | Ramanujan mathematician | ramanujan summation | Ramanujan infinite series | ramanujan infinite sum | Ramanujan infinite sum series | Ramanujan infinite sum proof | ramanujan sum of all positive integers minus 1/12th
