| Abstract: | The Euler constant is indicated with C. And fn(x) is led into this paper by author.When n approaches to fn(x) is compared with(fn(x)) of the second kind of Euler integral and C's another definition is also given by means of the generalized integral by the author.And in the end the author brings out the surmountable functions Ei(x), Li(x), Si(x) and Ci(x). |
