New Formula of Gamma function Approximation The Gamma function approximation gives a high level of accuracy for real x,
Notes 1. the natural logarithm of the Gamma function on the left hand side. 2. In mathematics, the Gamma function is an important function that many other special functions depend on. If the closedform of Gamma function is found, the chance of resolving the Riemann hypothesis is very high. Unfortunately, its existence is still not known.

We work on exploring and developing math series. Each time a series or a group of series has been developed completely, it is posted on this website. Below are the patterns of some series listed in date order. More related series can be found in the Series Outline section, which consists of Random Series and Series Summary. Random Series is a place where it keeps all math series without classifying to a specific type. Series Summary is a SMS's part in which it keeps the math series in relation to the dates posted on this website.

Note: the author, who created and posted these series on this page, sent 'the idea of these series' to a 'guy' who published the new findings based on Ramanujan's original series for requesting whether those series above are new. There were no answers but ... four months later that 'guy' published in his another article and indicated that the findings in his earlier publish was in the bad direction, and he recomputed his findings based on 'the idea of these series' without mentioning the source of the original inspiration leading to that change!
