Is it possible to prove that eulers constant is transcendental?

Yes. Do a search on "proof that e is transcendental" in your favorite search engine and you will find many proofs.

No,not nepiers constant, i mean euler mascheroni constant

Ah, I wondered about whether you meant Napier's constant, which I've seen also referred to as Euler's constant. From Wikipedia: Quote:

Thanx. Can you show me how the limit of the difference of the harmonic series and natural logarithm output such a number????? I think your explanation will be much easier than other text books.

That is simply how it is defined, from my limited understanding of it. I'm sure someone who actually knows something about this constant will weigh in.

I should mention that I think of as the logarithm of a more fundamental constant, Somehow it's natural that the limit, involving logarithms as it does, has a constant which is the logarithm of the fundamental one. I should mention at this point that is also believed to be transcendental but not even known to be rational. If it is rational the denominator is large.

But is it possible to derive euler mascheroni constant from that formula
