# Which is greater, $\cos(\cos(1))$ or $\cos(\cos(\cos(1)))$?
What is the simplest way we can find which one of $\cos(\cos(1))$ and $\cos(\cos(\cos(1)))$ [in radians] is greater without using a calculator [pen and paper approach]? I thought of using some inequality relating $\cos(x)$ and $x$, but do not know anything ... | {} |
Not too long ago, I discovered that I can actually skim the arXiv quite fast with RSS feeds. Skimming the headlines in hep-ex, you can just ignore anything with “unparticle” or “New limits on [unmotivated model]-type models” in the title. For all other fields, if I can’t understand the title. I just skip it. The proble... | {} |

Why DES s-box non-linear? Why it makes the cracking of the cypher more difficult?
I know that if we have a cypher which makes only linear transformations (let's say a bunch of $XOR$'s), we break it simply writing a system of equations with $\oplus$ operation starting from the ...

Is every 1-periodic function integrable on $[0,1]$ bounded?
Suppose that $f:[0,1] \to \mathbb{R}$ is $1$-periodic, meaning that $f(x)=f(x+1) \ \forall x$, and $\int_0^1 f(t) dt < \infty$. Does this mean that $f$ is bounded ?
For general function, i know this is not true, for example $f(x) = x^{-1/2}$ which is not bou... | {} |

# full families of Hopfian (co-Hopfian) groups
Let $\{G_{i}\}_{i\in I}$ be a full family of groups. Then each $G_{i}$ is Hopfian (co-Hopfian) if and only if $\bigoplus_{i\in I}G_{i}$ is Hopfian (co-Hopfian).
Proof. ,,$\Rightarrow$” Let
$f:\bigoplus_{i\in I}G_{i}\to\bigoplus_{i\in I}G_{i}$

Things to keep in mind when grading:
• Transparency.
• Fairness.
• Explanation. Use grading as a teaching opportunity (by giving counter-examples, etc.).
Each TA focus group will be given four (4) questions, and 3 answers to each. Each TA will then grade these 3 papers with four questions each in the stipulated time.... | {} |

Lemma 9.22.3. Let $L/K$ be a Galois extension with Galois group $G$. Let $\Lambda$ be the set of finite Galois subextensions, i.e., $\lambda \in \Lambda$ corresponds to $L/L_\lambda /K$ with $L_\lambda /K$ finite Galois with Galois group $G_\lambda$. Define a partial ordering on $\Lambda$ by the rule $\lambda \geq \lam... | {} |
