Subject: LaTeX guide To use LaTeX on this board, you don't need any special tags like [tex] ... [/tex]. You just type in the appropriate codes right in your text. For example, you could write: Is it true that /sum/phi(n) = /Phi, or is it simply that /sum/phi(n) /approx /Phi? but using backslashes instead of slashes. This would give you: Is it true that ∑φ(n) = Φ, or is it simply that ∑φ(n) ≈ Φ? You can look at the following primer on LaTeX to see what the codes are for various symbols. Note that most of the symbols listed in the primer don't actually work on this board. Listed below are the symbols that work and those that don't. Here's the primer: http://www.physicsforums.com/misc/howtolatex.pdf All of the Greek Letters seem to work (that's the first set of characters in the primer), and none of the Functions seem to work (sin, log, etc). Also, the LaTeX super- and subscripting don't work, so you should use the standard HTML tags for that (which are [ sup ] ... [ /sup ], and [ sub ] ... [ /sub ], without the spaces). LaTeX fonts don't work either (mathbb, mathcal, etc). In the following, the code is given in bold if it is the code that works for the corresponding symbol on this site and said code is different from the one given in the above link. Miscellaneous Symbols we do have ∞ (infty) ' (prime) sqrt (sqrt) ∠ (angle) ∀ (forall) ∃ (exists) ♣ (clubsuit) ♥ (heartsuit) ♠ (spadesuit) Miscellaneous Symbols we don't have aleph hbar imath jmath ell wp Re Im partial emptyset abla top bot | triangle backslash neg flat natural sharp diamondsuit Large Operators we do have ∑ (sum) Π (prod) ∫ (int) Large Operators we don't have coprod oint bigcap bigcup bigsqcup bigvee bigwedge bigodot bigotimes bigoplus biguplus Binary Operations we do have ± (pm) · (cdot) × (times) • (bullet) ÷ (div) † (dag) ‡ (ddag) Binary Operations we don't have mp setminus ast star diamond circ cap cup uplus sqcap sqcup triangleleft triangleright wr bigcirc bigtriangleup bigtriangledown vee wedge oplus ominus otimes oslash odot amalg Relations we do have ≤ (leq) ≥ (geq) ≡ (equiv) ⊂ (subset) ⊃ (supset) ≈ (approx) ∝ (propto) ⊥ (per) Relations we don't have prec succ sim preceq succeq simeq ll gg asymp subseteq supseteq cong sqsubseteq sqsupseteq bowtie in ni vdash dashv models smile mid doteq frown parallel Arrows we do have ← (leftarrow) → (rightarrow) ⇒ (Rightarrow) ↔ (leftrightarrow) ⇔ (Leftrightarrow) ↑ (uparrow) ↓ (downarrow) Arrows we don't have Leftarrow longleftarrow longrightarrow Longleftarrow Longrightarrow longleftrightarrow Longleftrightarrow hookleftarrow hookrightarrow leftharpoonup leftharpoondown rightharpoonup rightharpoondown Uparrow Downarrow updownarrow Updownarrow nearrow nwarrow searrow swarrow mapsto longmapsto leftrightharpoons Edited by AKG on 12/22/05 - 1:03 PM |

So we can use latex on these forums? Do we use the <math> </math> tags? Looking at what is supported in latex, it appears that unicode is on a par with it. |

muxol, it's not actually LaTeX. I was going to mention that earlier but forgot about it. But all it is is symbol substitution. Type in backslash-sum (but an actual backslash instead of writing "backslash-") and the software will substitute it with the symbol ∑. The only purpose is so that people who are familiar with LaTeX can use a similar notation on this forum (not to mention that the notation makes a lot more sense than HTML character entities).

As mentioned elsewhere, I can add anything that has an html character code equivilant. I know there are a lot of things that have them not yet handled, but I don't have a list and am unlikely to get around to it unless someone makes it for me. |

Just wondering... is there a special charachter set I need to be able to see some of these symbols? The exists, forall and some others (like some of the arrows and sub/super set symbols) just appear as boxes... is there a way to remedy this? |

IIRC, box means a font problem, question mark means an encoding problem. You can try making sure in your options that you let the web sites you visit choose the font. If that doesn't work, what Browser/OS do you use? |

can we PLEASE actually get LaTeX to work on this board. It is worth the effort, this LaTeX/HTML hybrid stuff is not very efficient and is a waste of time to learn. |

If you bothered to actually point at something specific not working, then something might be done, but since you don't care enough to be specific there's no point in my wasting time on you. this LaTeX/HTML hybrid stuff is not very efficient This is the internet, in case you haven't noticed. Pages are HTML, period. Everything else must be translated to HTML. |

Unfortunately, rendering a good deal of symbols and expressions is still fairly unreliable amongst browsers/fonts/operatingsystems. :-/ I find these seems generally usable/supported: http://www.bigbaer.com/sidebars/entities/ http://www.cs.tut.fi/~jkorpela/HTML/guide/entities.html These pages offer some good details and standards (some only proposed at this point): http://www.unicode.org/charts/symbols.html Some comments here as well: http://www.cs.tut.fi/~jkorpela/math/#chars Hopefully, using www as a general medium for representing all kinds of expressions, will be more standardized (and supported) within the next few years. In waiting for this to crystalize, such metasites as wikipedia, has now implemented full LaTeX integration (by generating, and inserting, small images on-the-fly). |
