Math Is Fun Forum / Forum Features

MathsIsFun · 2006-02-22 22:21:40

Let's put all the different forum features here as an "easy reference".

The Hide Tag

We have a "Hide" tag, which lets you enter your answer but people have to click on a button to see it. This lets other people have a go without seeing your answer. It doesn't really hide it, but does remove it by one click.

You use it like this (use [] not {} ):

My answer {hide=is this}42 !{/hide}

My answer

The Math Tag

Allows you to use LaTeX to format math expressions very neatly.

See: http://www.mathsisfun.com/forum/viewtopic.php?id=1581
Also: A LaTeX tutorial.

Other Tags

Code:

M[sub]a[/sub]=x[sup]e[/sup] 
[color=#ccccdd]hhhdaba[/color]
[align=left]left[/align]
[align=center]center[/align]
[align=right]right[/align]
[hr]

M_a=x^e

left

center

right

Instructions for more basic tags can be found here.

Special Smileys

To make any of these work, put a ":" in front of the text:

alpha=α and=∧ ang=∠ asymp=≈ beta=β bull=• cap=∩ cong=≅ cup=∪
deg=° Delta=Δ delta=δ divide=÷ empty=∅ epsilon=ε equiv=≡ exist=∃
fnof=ƒ forall=∀ frac12=½ frac14=¼ frac34=¾ gamma=γ ge=≥
harr=↔ hArr=⇔ infin=∞ int=∫ isin=∈ lambda=λ laquo=« larr=← lArr=⇐ le=≤
mu=μ nabla=∇ ne=≠ ni=∋ notin=∉ nsub=⊄ omega=ω oplus=⊕ otimes=⊗
part=∂ Phi=Φ pi=π plusmn=± prime=′ Prime=″ prod=∏ prop=∝
radic=√ raquo=» rarr=→ rArr=⇒ rho=ρ
Sigma=Σ sigma=σ sim=∼ sube=⊆ sub=⊂ sum=∑ sup1=¹ sup2=² sup3=³ supe=⊇ sup=⊃
tau=τ there4=∴ theta=θ times=× xi=ξ zeta=ζ

I also did a trick with some of them, for example "pi" looks a lot more like pi really does (π vs π) because I used a different font for it.

Example usage:
π ≅ 22 ÷ 7

Code:

:pi :cong 22 :divide 7

hi. one quick question. how do i START a new post? i know how to reply to one like this, but how do i start one?

mathsyperson · 2008-03-21 07:51:50

The 'post topic' button appears when you're in a board (eg. Introductions). It's in roughly the same place as the 'post reply' button is when you're in a topic.

I haven't used the Hide Tag and Colour Tag for some time, and I'm just testing it out.

Thanks for the insight all. But i'd like to know how to make text bigger. I surf using my mobile phone and most times i find it difficult viewing the solutions to most math problems(and its not the font size of my phone as that have been moderately increased) ....and since the solutions come highlighted when i click instead of having it go bigger it ends up being distorted.

Hi;

Here is what I do. It doesn't work on all the forums that use latex but it works here.

Here's a List of 140 Named HTML Colors...

Just use the Name written in the colors to get the color (instead of writing the code --> #??????) and you're done!!

e.g {color=MediumAquaMarine}text{/color}

Note: Replace "{" and "}" in the above example with "[" and "]" respectively.

In some forum skins, this text is nearly invisible. Highlight the text.

Cool! I doubt anyone else knew all those colors. Looks like I won't need the Hexadecimal Colors tool anymore to get the right color!

What happens if you \Huge and \HUGE?

Interesting... It works with Huge, but not HUGE or Tiny.

:sqrt

Does this exist?

bob bundy · 2013-05-10 16:51:23

Do you want the latex command? try \sqrt{number in here}
