    Hm. (Posting in bold are we?). Texmaker doesn't seem to want to play. Going back I see the Schneibster has snuck a link into 'This' and 'This' isn't Texmaker. That ('This') looks minimalist. I'll have a play with it. Thanks.

    \(e^{i\theta}=\cos(\theta)+i\sin(\theta)\)
    Yaay. Mighty aches from tiny toecorns grow.

    Sure. If you learn the basics of LaTeX you'll find that this minimal solution will give you pretty much all you can handle (but maybe not those unbelievable things rpenner has been posting; I'm still pretty impressed with that stuff).

    Test

    Standard wavelength \( {\lambda} = \frac{h}{m c}\)
    Reduced wavelength \(\frac{\lambda}{2 \pi} = \frac{\hbar}{m c}\)

    1) \(\Omega _M = - 0.38( \pm 0.22)\)

    2) \( \Omega _R h^2 \approx 4.16 \times 10^{ - 5}\),

    3) \(\Omega _\Lambda = 0\)

    4) \frac{-b\pm\sqrt{b^2-4ac}}{2a}

    5)

    \( {U_{gs}} = | - \frac{3}{5}\frac{{G{M^2}}}{{{R_{gs}}}}| = M{c^2} \)

    {U_{gs}} = | - \frac{3}{5}\frac{{G{M^2}}}{{{R_{gs}}}}| = M{c^2}

    I was told that my site's \frac was broken not too long ago. \lfrac works still, but I haven't had the need or the energy to track down every package and all that...

    \( d{s^2} = - (1 - \frac{{2GM}}{{{c^2}r}}){c^2}d{t^2} + \frac{1}{{(1 - \frac{{2GM}}{{{c^2}r}})}}d{r^2} + {r^2}d{\theta ^2} + {r^2}{\sin ^2}\theta d{\phi ^2} \)

    can someone please troubleshoot this and see why the latex commands are not working?
    I have tested it with several tex editors and it displays fine on them, but not here. Thanks

    \( \frac { 1 }{ \sqrt { { \left[ 1-\frac { { \omega }^{ 2 } }{ { \omega }_{ c }^{ 2 } } \right] }^{ 2 }+\quad { \eta }^{ 2 } } } \)

    The plot thickens! Sometimes it shows up as a proper equation, and sometimes as just the tex commands. wtf?

    The current javascript/CSS-based renderer only runs at the time of page loads. Since the "submit new/edited post and redisplay page" logic of this side does so without a full load of the page, updates don't get the LaTeX-to-HTML Display treatment until you refresh the page.

    Ah, I think that was what I was seeing; the equation stays in the tex command format until the page is refreshed. But I never see it displayed as an equation in the post preview, only after posting. Is that normal?
    Thanks for your reply!

    My iPad doesn't show even a single correctly formatted equation here, even though my Mac does, which is why I don't bother.

    I want to go inline with \(E=mc^2\)
