Equations Suck

    Seeing people attach word docs to their posts in order to get their equations all pretty is a bit sad.
    What are the chances that this forum could use MathJax? or something similar?

    I've passed this onto our IT guys. We've wanted to do something for a while - unfortunately our IT team is stretched and it'll require a couple of days of their time to implement - so we've not been able to do anything yet. :(

    Well, lots of sympathy for the stretched IT guys.
    Time to sit tight and wait for the budget entrails to align I guess :)

    One of the IT team says he's sorted this and it seems to be working except for MathML...

    Care to try this out?

    A simple example:

    \[ \left [ - \frac{\hbar^2}{2 m} \frac{\partial^2}{\partial x^2} + V \right ] \Psi = i \hbar \frac{\partial}{\partial t} \Psi \]

    Hurrah! That is fantastic!

    Post exams are you up for writing a thread explaining to students how to use it? And I'll make sure it gets the attention it deserves.

    Will do. I'm looking into how to render the term-certain symbol - I have some code that works well in LateX but it requires some tweaking for a pure TeX environment.

    These \LaTeX symbols are useful...

    Hi 5 for your IT peoples!
     
  10. Any good Mathjax ways of getting a term certain symbol i.e. a thing like ¬ to sit over a number?

    I've tried overline with a pipe symbol | e.g. to show a ten year annuity certain payable in arrears:

    \[ a_{\overline{10|}} \]

    Great! Thanks John for taking this up - and the acted IT guys for implementing it!

    There is a way - a bit clunky at the moment (I've been trying to work out a way of embedding a simple definition in the page but no luck yet!). You need to first import a bit of the MathML package available by saying

    \require{enclose}

    and then you can typeset term-certain symbols with

    A_\enclose{actuarial}{n}

    Which produces
    \[
    \require{enclose}
    A_\enclose{actuarial}{n}
    \]
