Calculus I: infinite series
For what values of $0 < p \leq 1$ the alternating series $\sum_{n =1}^{\infty}(-1)^{n-1} \frac{\tan^{-1} n}{n^p}$ is convergent?
Answer. It is convergent for all $p\in(0,1]$. Solution. Due to Leibniz rule, it suffices to prove that $f(t,p):=\frac{\mathrm{ArcTan(t)}}{t^{p}}$ is decreasing fo... | 5 | [

Zeisel Numbers
Helmut Zeisel found that p = 2^(k-1) + k is prime if k=1885. The
number 1885 is also interesting for another reason: It can be
factored as 1885 = (1)(5)(13)(29). Notice that
(1)
(5) = 2(1) + 3
(13) = 2(5) + 3

I have a sorted array of integers of size n. These values are not unique. What I need to do is : Given a B, I need to find an i<A[n] such that the sum of |A[j:1 to n]-i| is lesser than B and to that

From: Ralph Sierra
Subject: Help, please!
I'm a student in high school and I need help on this one problem.
I'm in geometry and stumped. I'm thinking that maybe to figure it
out, it needs to be said that if 2 sides of a triangle are not
congruent, then the a... | 4 | [

The fixed points and periodic orbits
The first derivative of quadratic map f(z) = z^2 + c at a fixed point z[∗] = f(z[∗ ])
λ = f '(z[∗ ]) = 2z[∗]
is a complex number called multiplier (or the eigenvalue) of the point. In particular, f ' = 0 for critical points of f. For small enough ε
f(z[∗] + ε) = f(z[∗ ]) + λ ε + O(... | 4 | [
