Back in the day I watched your parkour tutorials. Now here I am learning how to take math notes in Obsidian for school. It feels like I've come full circle

Just discovered Obsidian and my first question was whether or not I could use it to take my engineering notes. So AWESOME!

Thank you! This video has been so helpful for my Chem equations!

Thanks so much for the tutorial! Makes my obsidian notes much better looking now!

Muchas gracias. Estoy iniciando en Obsidian y estaba buscando la manera de escribir matemáticas y, definitivamente lo has logrado. Tu explicación es muy intuitiva y formativa. Mi hijo de 10 años ha estado fascinado con lo que ha aprendido. Gracias. Saludos desde México.

Awesome awesome video Bryan! Thanks for sharing!

This is great and super helpful. I am preparing for university math and wanted to make notes in obsidian to refer to. With dyslexia that Extended Mathjax plugin is going to be a HUGE help, thanks so much Bryan!! :-) Much appreciated!!

Amazing video man... just discovered Obsidian and it has been blowing my mind so far with its capability.

Awesome as always!

Gracias Bryan. Me has absuelto varias dudas.

Good video! Although matrices can be done much better than shown in the video. Manually setting the size of the braces isn't great. If you use the left and right commands followed by the braces, e.g. "\left( xxx ight)" or "\left\{ xxx ight\}", the braces automatically adjust to the correct size based on the thing inside. And even simpler; instead of {array} simply use either {pmatrix} or {bmatrix} for matrices with parentheses and square brackets.

Thank you very much for your video! Before I couldn't totally follow the tuto because I was on iPad but now that I have a pc I understand a lot about MathJax, Just one problem, I can't find the Math-Jax plug-in at all, in the community plug-ins. Because otherwise I don't know how to increase the size of the text with the other latex plug-ins. Would anyone know how to do this, please?

In addition to showing how to use LaTeX in Obsidian, this might just be the best beginner tutorial for LaTex syntax in general. Wish this was around when I started grad school. :P

just needed to know how to put a sentence in 2^(sentence) just into the video and noticed oh just putting { } works thanks

The laTeX colour preamble, couldnt find if u had posted this anywhere so wrote it up manually incase someone was looking and couldnt find: \definecolor{light}{RGB}{235,219,178} \definecolor{gray}{RGB}{146,131,116} \definecolor{b-red}{RGB}{251,73,52} \definecolor{b-green}{RGB}{184,187,38} \definecolor{b-yellow}{RGB}{250,189,47} \definecolor{b-blue}{RGB}{131,165,152} \definecolor{b-purple}{RGB}{211,134,155} \definecolor{b-aqua}{RGB}{142,192,124} \definecolor{b-orange}{RGB}{254,128,25} \definecolor{n-red}{RGB}{204,38,29} \definecolor{n-green}{RGB}{152,151,26} \definecolor{n-yellow}{RGB}{215,153,33} \definecolor{n-blue}{RGB}{69,133,136} \definecolor{n-purple}{RGB}{177,98,134} \definecolor{n-aqua}{RGB}{104,157,106} \definecolor{n-orange}{RGB}{214,93,14} \definecolor{f-red}{RGB}{157,0,6} \definecolor{f-green}{RGB}{121,116,14} \definecolor{f-yellow}{RGB}{181,118,20} \definecolor{f-blue}{RGB}{7,102,120} \definecolor{f-purple}{RGB}{143,63,113} \definecolor{f-aqua}{RGB}{66,123,88} \definecolor{f-orange}{RGB}{175,58,3}

Here, I have summarized what I have understood from this video. This is my very first introduction to latex or mathjax so there might be mistakes in it. I have skipped the colour part. Thank you very much Bryan for such a great lecture!! Comments will be highly appreciated. Happy Learning... :-) 1. $A=5$ 2. This is an inline equation ''$\sigma$'' for you. The \ is used to enter the command which is sigma. 3. Here you can see $sigma$ is considered as plain text without the \ sign. 4. This is a centred equation $$A=\sqrt2$$ for you. Here \ is there before A because A is not a command but 'sqrt' is!! 5. This is how you write $\pi$. 6. \$\pi$ $\pi\$ So if you put \ before $ or any command then it will escape the $ sign as a result the $ won't do anything. It will automatically make the sign Grey. It says to latex that oh nono it's plain text only. 7. $\textbf{Text}$ this command will make text bold. 8. Some COMMANDS will take INPUT by '\' Whereas, some commands will take INPUT through {}. Eg. $\textbf{BOLD}$ 9. Certain other equations can take OPTIONAL INPUT. Eg: $\sqrt4$ > $\sqrt[n]4$. Here [ ] is taking optional input. 10. $\sqrt444$ here sqrt is only on the first 4. To cover the whole number have to use { } after the sqrt command $\sqrt{444}$ $\, \, \,$This will tell sqrt that the whole thing is together/one unit. 11. To get extensive knowledge about the $\textbf{SYNTAX}$ will have to go to the latex or mathjax sites. 12. Let's see some commonly used syntax: 13. $x^2$; "^" is used to take things on SUPERSCRIPT. 14. $x_2$; "__" is used to take things to SUBSCRIPT. 15. $\frac{1}{\sqrt2\pi nd^2}$; This is how FRACTION can be inserted. Here after "pi" there is a space, whitout which it will look like $\frac{1}{\sqrt2\pind^2}$; as latex is not recognising "pind" as a symbol/command. (Notice that there is no space in the result, whereas using a space command like '\\,' will actually make space between the symbols. Eg: $\pi\,x$ vs. $\pi x$) 16. Going really crazy with fractions: $$\frac{\pi ho h\sqrt{x}y^2d_2}{\frac{\sqrt{g^2+\frac{v^4}{R}}}{\frac{(2n-1)v}{\sqrt{\gamma RT}}}}$$ 17. Diffrent sections: $$\pi ho h\sqrt{x}y^2d_2$$ 18. $$\frac{\sqrt{g^2+\frac{v^4}{R}}}{\frac{(2n-1)v}{\sqrt{\gamma RT}}}$$ 19. $$\sqrt{g^2+\frac{v^4}{R}}$$ 20. $$\frac{(2n-1)v}{\sqrt{\gamma RT}}$$ 21. $$(2n-1)v$$ 22. $$\gamma RT$$ 23. Let's see some cases: $X^y_z$ & $X_z^y$ same result. So both subscript and superscript is applied to X; Again $\sqrt4^x_y$, $\frac{2^a_c}{3^b_d}^x_y$ 24. Moreover, $X^y^z$ and $X_y_z$ doesn't work; so to provide superscript of a superscript or subscript of a subscript we need to use ''{ }''; Eg. ${X^y}^y$,${X_y}_y$; Here { } is considered as same unit by "^" and "_" ; More examples: ${X^y_z}^y_z$; ${X^y_z}_z^y$. So anything inside { } is cosidred as same unit by the functions when seen from Both LEFT to RIGHT and RIGHT to LEFT!! 25. $\sqrt{44})^5)^7]_9$; Just some properties of ( ) & []. 26. $$\sum_{j=0}^nJ^2$$; in this {j=0} acts as subscript and n acts as superscript(refer to no. 23). So \sum_{j=0}^n acts as one unit then after that j^2 is just the next thing linearly to be printed, it doesn't have anything to do with the previous part. It shows that it is like writing a sentence of mathematics that has many words(chunks of functionality). 27. $\mathcal{Fraction\,\,\,\frac{2}{3}}$ vs $Fraction\,\,\,\frac{2}{3}$ ; //caligraphic letters rendering// 28. $\sigma\,\,\Sigma\,\,\delta\,\,\Delta\,\,\ldots\,\,\vdots$ $2,3,\,\ldots$ Some commonly used greek latters. 29. Let's see fencing: 1. $(x)$ 2. $[x]$ 3. $\{x\}$. (refer No. 6) 4. $$ 5. $\langle x angle$ 6. $|x|$ 7. $\|x\|$ 8. $||x||$ 30. $$ \begin{array}{rcl} 4&8&9\\ 4&2&8\\ 6&5&0\\ \end{array} $$ ''\begin'' starts an Environment and ''\ends'' an Environment. Inside the environment we have put an Array(\begin{array},\end{array}). Then {rcl} is there for allignment(right,centered,left). "&" renders a gap between the items. Double \\ breaks the line. It only works inside an begin and end environment. Let's do fencing: $$ (\begin{array}{rcl} 4&8&9\\ 4&2&8\\ 6&5&0\\ \end{array}) $$ Ughh not perfect! Using \Bigg and \bigg $$ \Bigg(\,\begin{array}{rcl} 4&8&9\\ 4&2&8\\ 6&5&0\\ \end{array}\,\bigg) $$ \Bigg is bigger and \bigg is smaller. 31. Now spacing: $x\!y$ $x\,y$ $x\:y$ $x\;y$ $x\quad y$ $x\qquad y$ 32. $$X_k=\frac{1}{N}\sum_{n=0}^{N-1}x_ne^{i2\pi k\frac{n}{N}}$$

Incredible

Honestly i was avoiding Latex but after your video i found it purely logical thanks

As a student in Data Science and an Obsidian user, you're the perfect channel to go to. There is just so much to learn from you, that's terrifying ! Thank you for this excellent video on LaTeX in Obsidian. I still have an unresolved question: is it possible to draw in LaTeX (wich I just discovered in your video) inside Obsidian? Many websites demonstrate how to trace lines, plans, circles... in LateX but I can't find a way to run these codes in Obsidian. Thank you x1000.

Super video! Thanks for putting this together! Curious, how did you get the editor and output windows to pop up at the same time so you see what the output looks like as type?

Thanks Bryan, loved the bit about colours. Do you have any thoughts on how to make local scale adjustments within a note? I want to display a particular equation as much bigger than others within the same note. Not having much luck with ewcommand or \def type solutions so far...

How do i code the black background with the colored code style? Thanks

@8:07, do I need to put that css line of code in my css snippets folder in order for it to work? bc i just put it under an equation for experimenting w/ latex and it did nothing.

Maths student over here. *gets popcorn out :P

Just WOW & just one question. I would like a formula sheet. How do I put large formulas into the 2nd column of a 2 column table and formula names in the first column with lines around each cell and formatted nicely with padding and using the entire text area width on the page.

Excellent tips and nice overview! Quick question: Can you autonumber equations in Obsidian? Since I'm from a science background, numbering and referring to equations must not be too contrived.

I don't know how I have been surviving with Evernote until now. Obsidian is freaking awesome!

Hi Bryan, which CSS did you change to make the equation looks bigger? I have this situation where my formula looks too small. I'm using Obisidian in MacOS Big Sur and Windows

28:50 why am i only able to do 3x3 matrixes? if i do bigger dimensions, the brackets wont adapt...

Thanks for your kind expression. I searched the tool or site about easy way of translation between pdf to latex. mathpix snip is the name of tool, but I want to use the tool with obsidian together. Cloud you recommend the way to use or tips?

It is recommended to use \(...)\ and \[ ... \] for inline and display style math rather than $ and $$. An interesting tidbit on LaTeX math is that you can sometimes copy equations straight out of Wikipedia and simply insert them into your LaTeX document.

hey my friend, thanks for your great work! I have a question, I dont have the math command in the command palette (strg+p) to quickly spawn $$$$, how did you get it? :)

Nice video. My only problem with mathjax in obsidian is the inability to change the way we input our equations. I put most of my theorems to anki where you insert mathjax by writing equations inside \( \). It would be sooo much easier there was a way of writing equations in obsidian like you do in anki instead of $$

thank you for the video. A question: Is there any way to use asciimath syntax? thanks in advance

is there a way to get suggestions for the latex commands if you start to write them?

Hi Bryan, How do you use Latex inside Obsidian to write a paper? I don't know anything about Latex but apparently the paper configuration is better and it would not break the workflow in writing the document. That's why I would like to learn how to use it.

Is there any way to make mathematical graphs in Mathjax. I know you cant use tikz and other packages, but is there some other solution?

Minha anotações ficam estranhas, as letras e números não ficam ordenados e ficam se sobrepondo, como fez pra fonte dos seus cálculos ficar assim?

Do you happen to have the preamble.sty available anywhere?

8:16 How do you do to insert code please, thank you so much btw for the tuto vid 🙏

May you tell me how you were able to render the LaTex code? I could not find how to open the complied view to the right side of your screen.

Amazing Tutorial!!! Thank you! Is there a way to write LaTeX without Having Obsidian italicizing the latex code?

Is there a way to enable equation numbering? Other apps like Typora support this.

how can math formulas be automatically be enumerated in Obsidian with LaTex code?

yea for Matrixes you could use \begin{bmatrix} 1 & 2 & 3\\ a & b & c \end{bmatrix} so that the {} wont get to small if you use more than 3 lines

Easy subscribe

someone knows, how can LaTex stored in a mySQL database be represented/rendered into the webbrowser as mathematical formulas?

32:35 is the thing I’ve been always wanting

How did you open this console? 36:44 I press Ctrl+P, but there is no any "Red" or "Yellow" (and yep, I download this plugin)

Do you have ideas how to make an easy way to format definitions, lemmas, examples in a unique way to set them apart from each other

Great video.. I am looking for building Spring/Java API to run complex algorithm/formula. seems that wolfram alpha may work.. however its bit costly.. please suggest on open source library or alternatives to wolfram.

Hi, can't seem to find your preamble file in the download from your website?

🐄

🐮

It seems that obsidian doesn't (yet) support equation numbering and \label and ef.

28:56 You can actually autosize your curly brackets using \left\{ and ight\} so you have: $$ \left\{\begin{array}{rcl} 0&6&7 \\ 9&7&3 \\ 6&4&1 \\ \end{array} ight\} $$

Came here to write the quadratic formula in Remnote. Leaved here subscribed. Edit: Leaved doesn't sound right but I can't think of what it should be

🐄I can't get the color coding to work. I added your templates to my templates folder. I have the preamble from Google Drive. I did the reload after directing the Extended plugin to my preamble in my vault folder. Typed out a $$\color{bred}X=$$ and nothing. Removed my theme and nothing. Edit: I got it to work using obsidian-mathjax-preamble-manager with BRAT.......huh. My head hurts.

La tech

How to create links to equations like this: formula (1) And then refer to this equation without remembering its number, and if I change the numbering of the equations, it will change everywhere.
