There is some controversy about typesetting the derivative with some people feeling that the d in dy/dx should not be italicised. Since, currently I am using /frac {dy}{dx}, mine are italicised.

 

a) How do I do a derivative in Author "correctly". (e.g. /d and /diff don't work)

b) Does it matter.

    I like to typeset these non-italicized, but I think the answer to question b) is no, not really.

     

    If you want the 'd' in derivatives in roman font, do this:

     

    \frac{\text{d}y}{\text{d}x}

     

    Putting anything inside \text{} will result in romant text, not math italic.

    The font used in \text{} is the background font, which in my case is not times

    Then try \mathrm{d} instead, which should give the roman version of whatever math font you're using.

     

    What fonts are you using? What font do you want the d to appear in?

    I am using the default Font in one of the Author templates which is Helvetica. In that same template, the default Maths font is Times, which I think is right. The main issue is not the font but the automatic italicising.

     

    I will try \mathrn{d}, thanks.

     

    BTW, is there a definitive list of what subset of LAtex actually works in Author?

     

    For example, I found /left({}/right) works by trial and error.

    I have not found how to do a long division yet.
