About the Euler-Mascheroni Constant: γ = ∫_0 ^1 (1/(1 − x)) + (1/(ln x)) dx We can see that 1− x ≠ 0 ⇔ 1 ≠ x ; x = 0 → ln x ∄ . If x ≠ 0 and x ≠ 1, in the Cartesian Plane, this function has singularity x=0 and x=1. So, I could write f(x) = (1/(1 − x)) + (1/(ln x)) ∫_0 ^1 f(x) dx = lim_(A→0^+ ) lim_(B→1^− ) ∫_A ^B f(x) dx ? PS: Sorry by my worse English
