Hn = S2 n+1 n! H n = S n + 1 2 n! Where S S denotes Stirling numbers of the first kind. But it may not be considered a "closed form", since Stirling numbers are not much more easy than …

Why is 1 1 not considered a prime number? Or, why is the definition of prime numbers given for integers greater than 1 1?

15, జన 2013, · Possible Duplicate: How do I convince someone that $1+1=2$ may not necessarily be true? I once read that some mathematicians provided a very length proof of $1+1=2$. Can …

5 One can write 1 + 1 2 + 1 3 + ⋯ + 1 n = γ + ψ(n + 1) 1 + 1 2 + 1 3 + + 1 n = γ + ψ (n + 1) where γ γ is Euler's constant and ψ ψ is the digamma function. Of course, one reason for creating the …

The factor 1/3 attached to the n3 n 3 term is also obvious from this observation. You can use induction to show that the lower-order terms can be dealt with using lower order expressions …
