Wow... Hi! ^.^

wave Hello, I was googling vector formulas for my precal final exam tomorrow, because I lost the sheet our teacher gave us, and found this site. I'm amazed, I had no idea there was a forum just for math!

I'm a junior in high school (soon to be a senior O.o). This forum looks to be very useful in the coming months, since I will be in AP Calculus BC next year. I hope to get to know this site fully, and lots of people on it too  =B

Incidentally, what are the [math] tags for? I mean, what do they do? =P

Hi hermione_brains!

the [math tag helps you use LaTeX to format your equations for better display.

e.g.

[math]x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}[/math]

will produce...

Hi hermione_brains;

Welcome to the forum!


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Hi iLink-9000;

I thought it was the other way around. Welcome to the forum.

Thanks ZHero! So, the forward slashes separate the different... terms, for lack of a better word, and the {}  brackets group them? frac is fractions... anything else? What if you wanted to use a subnumeral?

And I think it works either way, sometimes it's hard words for easy ideas but others it's easy words for hard ideas =DDD

Hi hermione_brains;

Use shift key and then minus key, and wrap what you want subscripted in {}. So it is A_{23} would get.

You can just right click on anybody's latex to see the code that produced it.

Re: Wow... Hi! ^.^

Yes! The forward slashes "" can either be used to separate "terms", to introduce "single space" or to use "special symbols".

Like...

[math]This \ is \ text.[/math]


[math]\text{Its better to use "text" preceded by a slash!}[/math]


[math]ten \ \ \ \ \ \ \ \ \ \ \ spaces[/math]


[math]\pm \ \mp \ \sum \ \rightarrow \ \Uparrow \ \star[/math]
