# Lim (x,y)->(0,0) (x^2*sin^2(y))/(x^2+2y^2)

## Homework Statement

lim (x,y)->(0,0) (x^2*sin^2(y))/(x^2+2y^2)

## The Attempt at a Solution

I have attempted to solve this by letting y=x giving me

lim (x^2*sin^2(x))/(x^2+2x^2) = lim x^2sin^2(x)/3x^2 = sin^2(x)/3 = 0
(x,x)->(0,0) (x,x)->(0,0)

And by letting both x and y = 0, both of which gave me the limit as being equal to 0 (left out equation, but can add in case I'm doing something wrong). The problem is that while all of these have given me a limit equal to zero, I don't know when I'm done and can say that the limit equals zero. We haven't gone over substituting in polar coordinates and when I tried to see how to do that I ended up confusing myself. Any easy to follow steps? (I did look back at other topics with the same problems, but wasn't able to work it out)

Technically speaking, you're never done. That's because you have to prove that the limit exists approaching 0 for every path. We obviously can't prove EVERY path, because there's an infinite amount of paths approaching (0,0) from every direction. So we basically accept that the limit exists once we've proven that it exists from an acceptable number of paths... there really is no particular number of paths to prove...

Some other paths you might want to try:
y= (-x)
y= αx (if the limit you find has α in it, then it relies on α and the limit would then not exist)
y= x2

Cylindrical:
(just substitute)
let x=rcos∅ and y=rsin∅

OK, so if I prove that the limit exist using, say, 5 or 6 different paths and they all come out to be zero, then I would be able to say that the limit exist, knowing full well that we haven't gone over every possible pathway? I keep reading that polar coordinates are supposed to be helpful with this topic, but he refuses to teach it and doesn't want us to use them if we know them. (Don't ask, it's a long story)

Sorry, I'm just trying to understand. It seems more like we're trying to prove the limit doesn't exist more then anything else.

That's exactly it. It's much easier to prove that it doesn't exist than to prove that it does. Say you prove it doesn't exist just once... well then, it doesn't exist.

And yes, you could show it exists for 5 or 6 paths, knowing that you haven't tested them all... and the general consensus would be that it does exist... but some genius may just come along and prove you wrong by some obscure path.

This guy has some good examples and explanations on multivariable limits:

(I did look back at other topics with the same problems, but wasn't able to work it out)

If I were doing it I would first note that as y -->0 we can replace sin(y) by y in your function F(x,y), so I would look at F1(x,y) = x^2 * y^2 /(x^2 + 2y^2)., which is >= 0 for any (x,y) not (0,0). Next I would note that if I have a smaller denominator I would have a larger fraction, so I would look at F2(x,y) = x^2 * y^2/(x^2 + y^2), because we have 0 <= F1(x,y) <= F2(x,y). Then in F2 I would switch to polar coordinates.

Thanks a lot. I think I get it now, and the video did help some. I am going to work on using polar coordinates, even if we aren't allowed to use them. Seems to be handy even I use it just to check. Thanks again.

### Gibbs Free Energy and equilibrium

In lecture on Friday in the notes it said if G(r) does not equal G(p) then the system (rxn) is not at equilibrium. Can someone explain why that is?

### Re: Gibbs Free Energy and equilibrium

Equilibrium means the forward rate equals the reverse rate. Free energy refers to the amount of energy available to do work. So when the energy of the reactants/products aren't equal, the system is not at equilibrium.

### Re: Gibbs Free Energy and equilibrium

It is also important to note that if deltaG = 0, then the rate of the forward reaction equals the rate of the backwards reaction, meaning that the reaction is at equilibrium.

The simplest way is probably using the CDF, which is known in this case. Let $X \sim Exp(1)$ and $Y = \sqrt{X}.$ The CDF of $X$ is $F_X(x) = 1 - e^{-x}$, for $x > 0.$ Then $$F_Y(y) = P(Y \le y) = P(\sqrt{X} \le y) = P(X \le y^2) = 1 - e^{-y^2},$$ for $y > 0.$ Then take the derivative of the CDF of $Y$ to get $F_Y^\prime(y) = f_Y(y) = 2ye^{-y^2},$ ...

Let $Y = E(X \mid G)$. Note that $$\int X^+ - X^-\, dP = \int X\, dP = \int Y\, dP = \int_{Y>0} Y\, dP + \int_{Y<0} Y \, dP = \int_{Y>0} X\, dP + \int_{Y<0} X \, dP$$ More over since $X$ and $Y$ have the same distribution $E [|X|] = E[|Y|]$.

It sounds like you want to generate gamma-distributed random variables. If you want to write the code yourself, the way I know how is using the acceptance-rejection method by first generating an exponentially-distributed RV. An exponential random variable $G$ with pdf $\lambda \mathrm e^{-\lambda g}$ may be generated by first generating a uniform(0,1) ...

The median for a random variable $X$ is $m$ such that $P(X \le m) \ge 1/2$ and $P(X \ge m) \ge 1/2$. In the first example the correct answer is $0$: $P(X \le 0) = P(X = 0) = 0.728303$ and $P(X \ge 0) = 1$. In the second example it is $2$: $P(X \le 2) = 0.10 + 0.20 + 0.30 = 0.6$, $P(X \ge 2) = 0.30 + 0.25 + 0.15 = 0.7$. Your method is completely wrong.

Outline: The sum is $\le 1$ in several possible ways. (i) One of the $X_i$ is $1$ and the rest are $0$. The probability is $\binom{4}{1}(0.1)(0.3)^3$. (ii) There are four $0$'s. Easy. (iii) There is no $1$, and there are three $0$'s, (iii) There are no $1$'s, there are two $0$'s, and the sum of the remaining $2$ random variables in $\le 1$. Apart from ...

I assume $X_1,X_2$ are independent.

The word "chance" is very loosely used in the question. Let's examine the case for 5 riders. If it is the expected value that is sought, E[x] = np, so for 5 riders, $5\cdot\frac15 = 1$ If it is the probability that is sought, P(none of the 5 have a puncture) = $(\frac{4}{5})^5 = \frac{1024}{3125}$ Thus P(at least one puncture occurs) = 1 - ...

$\textrm{Bin}(n,p)$ converges to $\mathcal{P}(\lambda)$ when $n\rightarrow +\infty$ and $np\rightarrow \lambda$. So these probabilities are only asymptotically equal.

I'll take the statement "All players are equally skilled." to mean that every player has a $50\%$ chance to win against every other player. $7$ players have been eliminated by $p_5$; the probability that $p_1$ was not among them is $24/31$. If $p_1$ has not been eliminated, the identity of the winner of $p_5$'s branch of the tournament is irrelevant to her; ...

It's the factor $0.6^2$ that takes into account the possibility of prisoners escaping before the third day. On each day, the probability of a prisoner escaping is $0.4$, so the probability of the prisoner staying is $0.6$, and this is squared because there are two days before the third day on which the prisoner might escape.

If $x$ is a real number then $e^x$ is a positive number less than $1$. The logarithm of a positive number less than $1$ is a negative number. $e^\text{something negative}$ is a positive number less than $1$. It has a logarithm. Its logarithm is negative.

The terminology may be a bit confusing, but when we say $Y$ is lognormally distributed, that means the logarithm of $Y$ is normally distributed. In other words if $X \sim \operatorname{Normal}(\mu,\sigma^2)$, then $\log Y = X$, and $Y = e^X \sim \operatorname{LogNormal}(\mu,\sigma^2)$. Then it becomes clear that if $X \in (-\infty, \infty)$, then $Y = e^X ... 1 Here is another piecewise linear solution: Write $$f(x,y)={1\over2}\bigl((1+g(x,y)\bigr)$$ whereby the function$g$is defined by $$g(x,y):=\cases{x+y\quad&(-x\leq y\leq 0) \cr x\quad&(0\leq y\leq x) \cr}$$ in the sector$x\geq|y|$and has the required symmetries.

For the triangle distribution you have three parameters$(a,b,c)$where $$P(X<a) = 0\\ P(X>b) = 0$$ so you could use the$\min\lbrace X_i \rbrace$and$\max\lbrace X_i \rbrace$as pretty decent estimates.

Thus the product distribution is, for$-1\le z\le 1$, $$f(z)=\int_{-1}^1\frac1{\sqrt{1-x^2}}\frac{1}{\sqrt{1-(z/x)^2}}\frac1{|x|}\,1_{[-x,x]}(z)\,dx$$ ... 1 Let$X$be a standard$n$dimensional Gaussian.

# How do you solve 0.5x+63=2x-42?

Nov 10, 2017

First, make the decimal into fraction
$\frac{5}{10} x + 63 = 2 x - 42$
Transfer all the variables to one side and all the numbers to the other
$\frac{5}{10} x - 2 x = - 63 - 42$
Remember,
$2 = \frac{2}{1} , \frac{4}{2} , \frac{6}{3} , \frac{8}{4} , \frac{10}{5.} \ldots \ldots \frac{20}{10}$
So, we can write it as
$\frac{5 x - 20 x}{10} = - 105$
$- \frac{15 x}{10} = - 105$
Multiply both sides by 10
$\frac{- 15 x}{\cancel{10}} \cancel{10} = - 105 \times 10$
$\cancel{-} 15 x = \cancel{-} 1050$
$15 x = 1050$
$x = \frac{1050}{15}$
$x = 70$

# How to label bibliography items, books and articles and others?

It is possible to segment bibliography by type (https://www.overleaf.com/learn/latex/Articles/Getting_started_with_BibLaTeX):

\printbibheading

And its also possible to segment by section like explored at Segmented bibliography with name of section.

The last one is more interesting thought additionally I would like to quickly see which ones are books and which ones are articles.

Is there some way to label the items as books or articles (or online, or other types)?

May be present things like:

[1] [book] Leslie Lamport, LaTeX: A Document Preparation System, ...
[2] [article] Joel Falcou, Designing HPC libraries in the modern C++ world,
...

Optionally will be nice to customize a little, perhaps:

[1]    BOOK Leslie Lamport, LaTeX: A Document Preparation System, ...
[2] ARTICLE Joel Falcou, Designing HPC libraries in the modern C++ world,
...

Or:

[1] BOOK Leslie Lamport, LaTeX: A Document Preparation System, ...

[2] ARTICLE Joel Falcou, Designing HPC libraries in the modern C++ world,

Will it be too much to ask for different colors for diff types, like articles in red, books in blue? Or automatic color selection.

biblatex saves the entry type of each entry in the entrytype field. It can be printed with \printfield{entrytype}. The output can be styled with \DeclareFieldFormat{entrytype}.

All standard styles and most good contributed style know the general-purpose bibmacro begentry that is executed at the beginning of each bibliography driver.

Putting this together you might want to try

\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[style=numeric, defernumbers, backend=biber]{biblatex}

\DeclareFieldFormat{entrytype}{\texttt{@#1}}

\begin{document}
\cite{sigfridsson,worman,nussbaum,geer,cicero}
\end{document}

If you want a fancy alignment you may have to measure the width of the strings. This can be done using some internal commands

\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}

On Relativistic f-Divergences
Alexia Jolicoeur-Martineau

Wed Jul 15 04:00 PM -- 04:45 PM & Thu Jul 16 03:00 AM -- 03:45 AM (PDT) @
We take a more rigorous look at Relativistic Generative Adversarial Networks (RGANs) and prove that the objective function of the discriminator is a statistical divergence for any concave function $f$ with minimal properties ($f(0)=0$, $f'(0) \neq 0$, $\sup_x f(x)>0$). We devise additional variants of relativistic $f$-divergences. We show that the Wasserstein distance is weaker than $f$-divergences which are weaker than relativistic $f$-divergences. Given the good performance of RGANs, this suggests that Wasserstein GAN does not performs well primarily because of the weak metric, but rather because of regularization and the use of a relativistic discriminator. We introduce the minimum-variance unbiased estimator (MVUE) for Relativistic paired GANs (RpGANs; originally called RGANs which could bring confusion) and show that it does not perform better. We show that the estimator of Relativistic average GANs (RaGANs) is asymptotically unbiased and that the finite-sample bias is small; removing this bias does not improve performance.
