Math in Wikispaces

We’ve just released a very powerful way for people to use mathematical formulas in their Wikispaces pages: LaTex support.

If you are familiar with LaTex, all you need to do is wrap your LaTex formula in [[math]] tags like this:

[[math]]
\tilde{f}(\omega)=\int_{-\infty}^{\infty} f(t) e^{-i\omega t}\,dt
[[math]]

That code will display this:

If you aren’t familiar with LaTex, now might be a great time to learn. Here are a couple of good resources.

Chapter 3, “Typesetting Mathematical Formulae”, of “The Not So Short Introduction to LaTeX2” is a good overview of LaTex math markup.

Andrew Roberts provides two sections on Mathematics in his “Getting to grips with LaTeX“.

Enjoy, and leave a comment with a link to your math pages.

    There is no need to learn LaTex. Use the free software Texaide to create the expression. Highlight and then copy the expression. Paste into the wikispaces editor. Remove unwanted text. Add the [[math]] tags. Example:

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

    I also use this approach when inserting an expression as text in GeoGebra.

    Excellent. For educational uses this is a big plus and another selling point. Thanks.

    LaTeX is very good, and the TeXaide tip was very good too… but I still don’t know how to put formulae inline, not just in a separate block. If anyone could help me…

    Mike, if you change your translation settings in TeXaide, you shouldn’t have any text to delete every time.

    [[math]]
    \[y = \int\limits_0^2 {\sin \frac{x}{2}dx}
    \]
    [[math]]

    can anyone help me with continued fractrions i.e. i want to know how i could write the Fibonacci numbers for example, in continued fraction form on the wiki.

    \cfrac{2}{1+\cfrac{2}{1+\cfrac{2}{1+\cfrac{2}{1}}}}

    Is it possible to have //inline// math formulas? As far as I can see, the only way to have [[math]] … [[math]] work is to let the markup, on a line by themselves, but this means that each formula takes a line by itself.

    As a workaround I may use a lot of \mbox{}es, see an example at http://xmau.wikispaces.com/test, but this is usually a mess :-(

    Right now, the only way is inside a block. Inline math formulas aren’t supported yet.

    Hey, do you know if it’s possible to insert math formulas within tables?
    Also, is it possible to support accents within \text{}? My site is in Spanish, so I have to use them a lot, but the page crashes if I insert an accent in \text{} environment.

    Thanks

    Hi Andrés,

    It’s not currently possible to put formulas in tables, but this is something that may change in the future. We’ll let you know as it does.

    Can you point us to a page that has a broken \text{} section with accented characters?

    Thanks,
    James
