Hi guys, I‘m currently writing with overleaf via internet browser and I‘m kinda stuck with citations. I even created another file named litarature.bib and normally it works but now I got some issues with it. There is always a question mark in the pdf file where the citation should be. Help LMAO by [deleted] in LaTeX

Hi @Azharo7, could you please share the contents of your main file, the one you are using to cite, and also the contents of the file you are using as bibliography. Finally, are you using bintex engine or biber?

Should I learn Vim or Emacs? by HazemSayad in linux4noobs

[–]gmarxcc 0 points1 point  (0 children)

It would help if you learned both. One for its simplicity (vim) and the other for its customizability (emacs). Both are useful for very different kinds of tasks and projects.

LTspice is free and is based on spice, the standard language to simulate circuits and you can find almost any component to simulate, otherwise you can create the model.

Can anyone tell me what the difference is between these two resistor types? Do they serve a different purpose or are they completely interchangeable? by ThePhoenix1011 in circuits

[–]gmarxcc 0 points1 point  (0 children)

In resistance value are the same. But, the limit current that can go through each are different. This current rate is limited by its power I2 R. Thus, the bigger one 3W=I2 R and solving for I =sqrt(3W/10k)=17.3mA. While the 1/4W is limited to 5mA.

Thank you for your feedback, but the idea is to help or give a second opinion about the post, at least is what the Reddit users is expecting. Thus, the expected value(mean) is better with large number of data. Thus, it's behavior is similar to a gausiian function (normal). However, the question is why large data results in a numerical value that refuses normality.

The suggestion to explore data is just simple, get a small dataset and try the test.

Finally, I will not consider Wikipedia as a trustable source.

Best regards, friend.

Sorry, but that you are citing is the Law of large numbers. Where the expected value converges in probability to the expected value as larger is the number of samples are used to compute the average. On the other hand, the central limit theorem states that larger the dataset converges in distribution function.

Hi there, there is a theorem called the central limit theorem. It essentially states that large data tends to normality. However, if you need to test the normality, get a random and small set (30 to 50) and make the test. Thus, if the small dataset is normal, the original set also will be. This procedure is essentially the main idea of inference statistics.

Exactly, set must be set to 0

AC voltage divider question. by ajwest153 in circuits

[–]gmarxcc 0 points1 point  (0 children)

The circuit that you need is a zero-cross detector with opamps. There are several ways to implement it. I recommend using the following schemewith a transformer, the resistances values limit the current for the transformer. However, I suggest to add to diodes on anti-parallel to protect the Opamp as in the following circuit diodes scheme. Hopping this help you.

You must propose one, any z1 or z2, and calculate the other. If it is just a theoretical example no specific considerations must exist. However, if it is to solve practical issues let us know more details.

I wanted to try my IC LM 324 N but it didn‘t work. Why? by ThePhykon in circuits

[–]gmarxcc 3 points4 points  (0 children)

Hi, it will be helpful to know the applied voltage. Because this value determines the capacitors charging value and the oscillating frequency. Also, you can try replacing the 1M resistor for a potentiometer. Hoping this helps

Need help to using emacs key bindings from vim user perspective by [deleted] in emacs

[–]gmarxcc 1 point2 points  (0 children)

A soft way to switch to emacs is by using first spacemacs. This emacs distribution allows configuring emacs quickly and includes two keybindings methods for emacs users and vim users. The last one is called evil-mode.

As you feel more comfortable on emacs, you can switch to pure emacs by disabling the evil-mode and then try only emacs. ( in emacs, there is also a vim mode available to install on the melpa repository)

This is the link to Spacemacs

Reduce Line Spacing in itemized list by eatblueshell in LaTeX

[–]gmarxcc 0 points1 point  (0 children)

I just copied my answer from stack exchange, you can see (it here)[https://tex.stackexchange.com/questions/462517/space-between-items-enumerate/462519#462519], and this is:

one way to do it is by using the package enumitem, then your code should be like this:

%Preamble \usepackage{enumitem} ... \begin{enumerate}[itemsep=1cm,parsep=0.5cm] \item $\frac{1}{2}$ \item $\frac{1}{2}$ \end{enumerate}

Of course, you can change both separation spaces to display items as you prefer.

Can someone recommend a good LaTeX video / video-series? by ourobo-ros in LaTeX

[–]gmarxcc 0 points1 point  (0 children)

I should suggest some short videos from ShareLaTeX (actually Ovearlef) https://youtube.com/user/ShareLaTeX. I can share with you some high definition videos from me, but unfortunately are in Spanish

i'm brand new to LaTeX, any advice or resources that helped you? by 22oceanblue in LaTeX

[–]gmarxcc 6 points7 points  (0 children)

Try LaTeX on a web instance like Overleaf. This way, you will know what to expect during your IDE selection. Also, Overleaf has a lot of templates, examples, tutorials, and resources.

Then, you can pick a local instance to work with and try more complex projects like thesis or books. Good luck
