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

[LucasDimoveo]

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

[ntx_ilpatgece]

@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.

[entusiastaX]

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.

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

[kritidiptadatta]

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: $$\frac{\pi\rho RT}}}}$$
17. Diffrent sections: $$\pi\rho h\sqrt{x}y^2d_2$$
18. 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$$; in this {j=0} acts as subscript and n acts as superscript(refer to no. 23). So \sum_{j=0}^n acts as one unit then after that j^2 is just the next thing linearly to be printed, it doesn't have anything to do with the previous part. It shows that it is like writing a sentence of mathematics that has many words(chunks of functionality).
27. $\mathcal{Fraction\, \, \, \frac{2}{3}}$ vs $Fraction\, \, \, \frac{2}{3}$ ; //caligraphic letters rendering//
28. $\sigma\, \, \Sigma\, \, \delta\, \, \Delta\, \, \ldots\, \, \vdots$ $2, 3, \, \ldots$ Some commonly used greek latters.
29. Let's see fencing: 1. $(x)$ 2. $[x]$ 3. $\{x\}$. (refer No. 6) 4. $<x>$ 5. $\langle x\rangle$ 6. $|x|$ 7. $\|x\|$ 8. $||x||$
30.
$$
\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)
$$
\Bigg is bigger and \bigg is smaller.
31. Now spacing:
$x\!y$
$x\, y$
$x\:y$
$x\;y$
$x\quad y$
$x\qquad y$
32. k\frac{n}{N}}$$

[calitreesweet]

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

[mhasondergaard]

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 \right)" or "\left\{ xxx \right\}", 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.

[zasushi]

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?

[fellowbuffellow]

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!!

[RePuLseHQKing]

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

[veronicahislop]

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

[stephenbazley]

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.

[Nana-wufb]

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

[zasushi]

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

[MrRubix]

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.

[lemonadeforlife]

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

[depth_and_breadth]

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

The laTeX colour preamble, couldnt find if u had posted this anywhere so wrote it up manually incase someone was looking and couldnt find:
