This problem was called Basel Problem. Bernoulli posed this problem. Leonhard Euler, a young man in his twenties proved it. It was a phenomenon in mathematical circles. Euler earned fame. He was called by the King of Prussia himself. He made mathematical theories due to which he is called 'King of Mathematics'. He has left so many theories that not all of them have been comprehended. He slowly began to loose his eyesight. But not his mathematical insights. Leonhard Euler was so great.
So Zeta(2) or Basel Problem or pi squared by 6 is given below as computed by consecutive numbers.
