This note has been created for everyone who needs help in $\LaTeX{}$ to ask their doubts so that we can become better at $\LaTeX{}$ as a Brilliant Community!

This discussion board is a place to discuss our Daily Challenges and the math and science
related to those challenges. Explanations are more than just a solution — they should
explain the steps and thinking strategies that you used to obtain the solution. Comments
should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .

Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.

Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

i know now how to write the start and end signs of latex start: "\$$("; end: "\)" in text by using \ \ ( \ ) ( \ \ ) without spaces.
but how to write \ [ and \ ] as text without spaces?

since u are much better in finding infos than i am: do you know if brilliant has anchors on their pages?
i would prefer to link to a chapter directly instead of linking a page and say "look at 2.13 Buttons".

You have comment anchors, but not anchors to specific points on notes. Those can only be done by the staff members. For comment anchors though, whenever you get a notification for a comment, and you click it, it will take you directly to the comment, use the link that is given for that page, and you can anchor that comment at any time :)

PS - Not really that good at this stuff, just got lucky that one time when i found it. Páll Márton is way better than me. He created the complete guide, found multiple things, like how to make cool shapes with latex, and how to make the unformatted brackets that you asked me for above. He created a line that is like a color pallet and has every color using latex, so its really him that can be considered the latex god of sorts lol

Páll Márton has (no activity) behind his name. (since he answered at leat once, i dont know if this "no activity" was auto-created)
and you are also great in figuring out stuff.
before u told me how to do it, i tried several \ [ combos, but they always produced a linefeed.
ty for the hint with the comment anchors.
again: you have a great knowledge. i took me a while to at least find out that these in-side-links are called anchors but you seem to know that already.

i just saw that your name is mentioned at the hidden text button in the latex guide. so this was no standard Latex feature? u invented it?

I was looking for breakfast, when i finished it I saw that you answered the question before me, no problemo :) @Hamza Anushath, Glad you foubd your answer @Elijah L

@Yajat Shamji hasn't seen my Latex-y solutions yet, or else the Latex Warden's mind would have been blown by now, in the BRILLIathon problems

$\begin{aligned} 2x - 5y &= 8 \\ 3x + 9y &= -12 \\ ha + m &= za \end{aligned}$

Yes, that's what I'm looking for, thank you!

@Elijah L, @Percy Jackson, is this what you guys were looking for?

\begin{align

Does anyone know how to align equations?

Log in to reply

Please elaborate, if you want me to help you @Elijah L

Log in to reply

So for example:

$x^2 + 2x + 1= 9$

$(x+1)^2 = 9$

$x+1 = \pm 3$

The equal signs are not vertically aligned, is there a way to vertically align them?

Log in to reply

@Elijah L - Try using \ [ \ ] instead of \ ( \ )

Log in to reply

$x^2 + 2x + 1 = 9$

$(x+1)^2 = 9$

$x+1=\pm 3$

(me trying to use \ [ \ ])

The equations are still not vertically aligned. They're centered, but not vertically aligned.
