Show by induction: $(1+\frac{1}{n})^{n}<n$ Show by induction that for all natural numbers n>3  $(1+\frac{1}{n})^n&lt;n$  Let $(1+\frac{1}{n})^n&lt;n$ be true !   We show that $(1+\frac{1}{n+1})^{n+1})&lt;n+1$  $(1+\frac{1}{n})^n(1+\frac{1}{n})&lt;n(1+\frac{1}{n})$   $(1+\frac{1}{n})^{n+1}&lt;n+1$  So now we just need to show that   $(1+\frac{1}{n+1})^{n+1}&lt;(1+\frac{1}{n})^{n+1}$  So here , If I show that :   $(1+\frac{1}{n+1})&lt;(1+\frac{1}{n})$   Does that mean im done with exercise ? How can I prove $\lim_{n \to \infty} \frac{n^2}{2^n}=0$ How can I prove $\lim_{n \to \infty} \frac{n^2}{2^n}=0$  I tried to use $\mid \frac{n^2}{2^n} - 0 \mid &lt;\epsilon $ However, because of $n^2$ I cannot use it. Also, I tried to use ratio test and I got $\lim_{n-&gt;\infty}\frac{(n+1)^2}{2}\frac{1}{n^2}$, but after that one, I dont know how to get limit &lt; 0  I have no idea to solve this problem.   I can also use a squeez lemma, but dont know how to apply to this question. If $$\tan(\frac{\pi}{4}+\frac{\theta}{2})=\tan^3(\frac{\pi}{4}+\frac{\alpha}{2})$$, then prove that $$\sin \theta=\frac{3 \sin \alpha+\sin^3 \alpha}{1+3\sin^2 \alpha}$$  I tried using the fact that  $\frac{\cos A}{1-\sin A}=\tan(\frac{\pi}{4}+\frac{A}{2})$ but now not able to eliminate $\cos \alpha$ and $\cos \theta$. How should I proceed? How to set a short password on Ubuntu? What happened to Finn's blaster at Maz Kanata's? When entering, we see that Finn has the blaster that was given to him earlier:    However, when the fighting begins, Finn tells Maz that he needs a weapon and no longer has his blaster with him.  It seems unlikely to have been lost in the first shots, given how it is secured across his body.  Also, Han and Chewie didn't lose their weapons and they are arguably less secure.  Now, when the team gets to the Resistance base, Finn again has his blaster:    So where was this blaster during the battle?

Is it known problem or am I only one? How do I fix it? Unsupervised learning for anomaly detection I've started working on an anomaly detection in Python.  My dataset is a time series one. The data is being collected by some sensors which record and collect data on semiconductor making machines.  My dataset looks like this:  ContextID   Time_ms Ar_Flow_sccm    BacksGas_Flow_sccm 7289973 09:12:48.502    49.56054688 1.953125 7289973 09:12:48.603    49.56054688 2.05078125 7289973 09:12:48.934    99.85351563 2.05078125 7289973 09:12:49.924    351.3183594 2.05078125 7289973 09:12:50.924    382.8125    1.953125 7289973 09:12:51.924    382.8125    1.7578125 7289973 09:12:52.934    382.8125    1.7578125 7289999 09:15:36.434    50.04882813 1.7578125 7289999 09:15:36.654    50.04882813 1.7578125 7289999 09:15:36.820    50.04882813 1.66015625 7289999 09:15:37.904    333.2519531 1.85546875 7289999 09:15:38.924    377.1972656 1.953125 7289999 09:15:39.994    377.1972656 1.7578125 7289999 09:15:41.94     388.671875  1.85546875 7289999 09:15:42.136    388.671875  1.85546875 7290025 09:18:00.429    381.5917969 1.85546875 7290025 09:18:01.448    381.5917969 1.85546875 7290025 09:18:02.488    381.5917969 1.953125 7290025 09:18:03.549    381.5917969 14.453125 7290025 09:18:04.589    381.5917969 46.77734375   What I have to do is to apply some unsupervised learning technique on each and every parameter column individually and find any anomalies that might exist in there. The ContextID is more like a product number.  I would like to know which unsupervised learning techniques can be used for this kind of task at hand.  Thanks $[K(\zeta_n):K]=\phi(n)$? Is it true that $[K(\zeta_n):K]=\phi(n)$ where $\zeta_n$ be primitive root of unity and K be field of char zero?  I think it should be equal to the degree of cyclotomic polynomial which has degree $\phi(n)$.  Can someone please elaborate that what is the procedure for finite fields Do you "gain" your 1st level? Why is the light in an airplane turned off during take off and landing? What do the various dpkg flags like 'ii' 'rc' mean? I frequently need to check which packages are installed, and I use the following command:  dpkg -l | grep foo  which gives the following output  Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Cfg-files/Unpacked/Failed-cfg/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name                       Version         Description ii   foo                       &lt;version&gt;         &lt;description&gt;    What does the ii mean?  What other flags are there? How to read the flags? (because the explanation is quite complicated, IMO)   Thanks. Show that $13$ divides $2^{70} + 3^{70}$.   My main problem here is trying to figure out how to separate the two elements in the sum, and then use Fermat's little theorem. So how can I separate the two?  Thanks! Is it possible to choose which OS will be loaded using a hardware switch?

I would like to do this via a command. In Harry Potter, Do Spells Travel in a Straight Line? In the Harry Potter world, when a magical person casts a spell, sometimes they target a specific object, like when Harry has a wand only and needs his broom, he casts "Accio Firebolt" and his broom comes to him.  But a lot of the time people point their wands just in the direction of someone to cast a spell.  One example would be in a duel.  When they do this, are they casting a spell on a particular person or at that person?  It seems, from what I remember of the movies, that some spells travel in a straight line while others specifically target a person or object.  Do any spells travel in one direction, like a laser beam?  What kind of spells are directional (instead of focusing on a particular person or object)?  And can directional spells be deflected or blocked by something like a mirror or another physical object?  (By "directional," I could have said linear, but didn't want to start sounding mathematical or scientific.  In other words, do they travel in one direction, like a laser beam would, or will they change direction to hit the intended target?) How to see the full date on macOS Big Sur? What are the criteria for posts to be included in "Top network posts" on new profile page? From the name of it, certainly it looks for posts with the highest scores. However, recently I found that some of the posts are not listed. Example: My  (not sure if it's that good, just because hot network question) was included in some point, but then it's not listed on . I guess it's because the question was closed, e.g as a dupe? (I don't have any hidden communities on the settings)    However, it's listed normally on .    Also, what other criteria that makes the posts to be included/excluded in &quot;Top network posts&quot;?
