I'm confused about wrote a root of function when plotting here graph with pgf-tikz. Any help is welcome.

I really struggle the get the Latex working for some reason, so I attached my attempted solution in another picture.

I'm using Visual Studio Code as my text editor. My ultimate goal is to use PythonTex in a Latex file so that I can generate multiple versions of the same worksheet for my class. As a test, I defined a variable myvar = "hi" but I can't get it to render correctly in the pdf when I use \py{myvar}...

Hi I’m working on a prototype idea and think I could greatly simplify one part if I used some sort of tough stretchy rubber. Something that offers good spring-like resistance and a fast rebound. I googled many different combinations of “latex like synthetic” or “stretchy synthetic rubbers”...

Hi, How do I left align the text below? Also, how do I create vertical spaces above and below the line stating "Subbing the following expressions..."? Could you please help me with it?To derive 14(ii) m_{0} \gamma^{2} \frac{d^{2} y}{d t^{2}}=e E_{y}^{\prime} from 13(ii) m_{0} \frac{d^{2}...

LaTeX is used widely in many disciplines and industries. It has this in common with other open standards which get a lot of development help and support from industry. Yet, we're still stick using a decades old version with packages taped on top that add features that should have been added to...

Hi, I'm using Scientific Workplace to write LaTex and it generates the code shown below for the given matrix. I don't think the generated code is standard LaTex in this particular instance. How can I fix it without making too many modifications? I mean if there is a simple way to fix it. Thank...

For many of the problems in my engineering courses (as well as other STEM courses and maybe even in industry), much of the work is in algebraic manipulation of equations. These problems could be solved using by using symbolic expressions in a coding language like MATLAB. However, it is very...

Hi, Question: How can I remove the extra spacing above the single-space equation environment. I have wrapped the equations in a single-space environment as the document has to be double spaced (and I wanted to save as much space as possible) From reading online, I have the following code at...

I am planning to type my equations in an offline LaTeX editor, simply because it is easier to do. I'll be using LyX. The problem is, it uses ##\#\#\#\###, for single line code, while my editor uses \$\$. Is there any way to overcome this? Am I, seriously, to replace every single \$\$ into...

Within the last year someone posted on a thread, it wasn't the main thread subject I think, a very useful seeming table of Latex which I think was interactive or semi-interactive. I thought note that and didn't and now can't find it. It would be useful to me right now, and think it would be...

Do people who learn LaTeX just practice it on their undergraduate assignments or something?

I do not know which forum I should turn to, so I post it here. If I should post it here, please help me move it. I want to delete those buttons at the bottom just before the footer. They are useless to me. I have googled them. But no relevant information shows up. Maybe I search them with wrong...

E very once in a while I see a post in which LaTex symbols appear that are absent from the primer offered in PF. Examples: \bf A in lieu of the awkward \mathbf A ## \ell ## for script l. There must olbviously be a list of the 28 letters that can be scripted. The font section in my LaTex...

Isn't it $$\color{red}x\color{black}y$$

Hi, How to draw Lewis diagrams, Lewis symbols , chemical equations in LaTeX?

When using latex for writing problems in physics, I find it difficult to make diagrams or figures (such as circuits, atwood machines, lenses, ...) so I wonder if anyone has some recommendations of programs or platforms that can make this "drawings" easy, possibly without the necessity of coding...

Hi again, I'm trying a new program, Scientific Workplace 6, which let's me produce a zip file with four different options as shown below. I just noticed that I could open these zip files in browser and format of the document remains intact. I only tried "Zip file with MathJax". Do you know...

Hi, doing some research for free Latex editors for Windows 10. I did an online search but would like to know the experiences of people with Latex editors, if any. Thanks.

Is it possible to typehttps://drive.google.com/open?id=186OoXjmVjb3nhXjSBKEAq2u_6MF-UXlm into LaTeX, or should I just print out the thing as it is? If the former, I do not know how I would go about it; the matrices seem much too wide for me to fit onto a letter-size page. For the record, the...

In the default installation of the gummi editor in Fedora, I find it difficult to locate LaTex errors. If I'm typing along and make a error in LaTex then the preview screen suddenly becomes a window saying no preview can be shown. I don't find the information in the "build tab" helpful. The...

I thought I'd make a new thread for some snippets of more "advanced" LaTeX codes that are not covered by the basic LaTeX tutorial. For example: \enclose{circle}{x} \enclose{circle}{x} A \overset{u}{=} B A \overset{u}{=} B A \overset{u}{ \rightarrow} B A \overset{u}{ \rightarrow } B A...

I have been to other forum sites too where we need to encode a mathematical statement like this ... , some sites use $...$ before and after the mathematical things and some sites like this great forum use [itex]...[itex]. Why it this so? The latex software like Texstudio, Texmaker etc. uses $$...

Hi PF! Does anyone know of a LaTeX editor that outputs white equations for powerpoints, etc.? I'm running a Mac, and currently use LaTeXiT, but I can't seem to get this to work for white output.

I downloaded the amsmath package and am using the command \usepackage{amsmath} and its not working. I have used it a few years ago, but can't remember whether I had this problem and what the solution was- I think it's something as simple as saving it in the right place if I recall quickly -...

I started reading QFT recently. With respect to the Dirac spinors, I was introduced to Feynman's slash notation: OR There are sites which say how this can be inserted in LaTeX documents. I checked out the LaTeX guide of PF, but found that it is not listed there. Writing...

As you can see in my attached picture, I am trying to continue on with my text after my embedded image, but it is putting the text still before the image. I'm not sure why it's doing this because I am writing the text after the \end{figure} command. Any ideas?

Hello, I am an artist working on weighted cloth in my practice since 2015. Each piece I make by hand and is extremely time consuming. I would love if someone would take a look at this and give me any thoughts you might have. I am working on a project that requires filling thin, fabric...

I suggest relabelling the "LaTeX guide" link, which is just below the reply box in threads. I think people who don't know LaTeX already don't necessarily recognise that this tells them how to write maths in the forum. Perhaps "How to write maths in the forum"? Also, the guide isn't linked at...

Hello, I've encountered a problem with the new software in that if I am editing a previous post when someone else replies to a thread, any Latex that I have in that post winds up getting garbled and the Latex removed. This has happened to me perhaps as often as half a dozen times or more...

Somebody on the Slack for one of my online classes shared this interesting mobile website where you can draw a mathematical symbol and get the LaTeX equivalent. http://detexify.kirelabs.org/classify.html

I cannot determine what the problem is. My latex codes have strange behaviors. This might be related to my PC. Fraction lines are disappearing. What is the problem? When I put reply button then preview it it looks good...

Every time I want to point a newbie to the latex tutorial I have to hunt it down myself. It would be really nice if there was a link or an icon right on the reply window to use in the post. Or am I missing something?

I've always pronounced it as its spell. It seems weird that you pronounce the x as a c/k.

I am writing a document for my students about the proper use of ##\LaTeX##. There are some things that always scorch my eyes, like improper italics [##sin(x)##] or incorrect typography of units [##128kg##]. I wonder those of you who are sticklers for typography have other pet peeves of the...

What is the latex code used in this forum of large bracket (and parenthesis) and subscript and superscript? For example, the below parenthesis is too small: ##(x1 + \frac{1}{\frac{1}{x1}})##

Please see the attached image for reference. I'm looking for a way to kind of "indent" in my steps to make it clear that I'm working on a subset of a problem. For example in this case, I want to evaluate each integral separately in kind of a sub step to so that everything is not running down in...

I want to write LaTeX. So I write e.g) '\left( \frac a b \right)' . But it looks just back space bar not mathematical equation. Does there need to install TeX program if I want to type LaTeX in Physics Forums?

I posted this link a couple years ago, but just in case you need to draw a Christmas Tree: https://tex.stackexchange.com/questions/39149/how-can-we-draw-a-christmas-tree-with-decorations-using-tikz There are a lot of interesting variations posted, maybe PF could have our own contest! Here's...

I wrote my first LaTeX like this: ... it was easy to calculate that $$ ê^1=\hat x - \frac { \hat y } {\tan \alpha} $$ and $$ ê^2=\frac { \hat y } {\sin \alpha} $$ where ... Is it possible to make the vertical separation smaller? The first example in the latex primer does not seem to suffer...

Can someone tell me how to write latex in this forum? Thanks

I enjoy writing in LaTeX and was wondering if it would be a bad idea if I wrote my notes up in LaTeX. Would I be better off just making handwritten notes for revision? Has anyone tried to revise by writing up concepts/equations in LaTeX and was it more useful than handwriting notes?

Hello all, So I've been trying to write some basic equations out like 1/2 but would like it to appear in a horizontal fashion (like 1 over 2). I have been reading threads on how to use latex, I've tried to look at others equations, right click and have the latex code shown to me so i can...
