So what I am trying to type is the square of the derivative of vector x. I tried dotvecx^,2 as well as dotvecx^2, but the outputs came out to be very offset. Is there a correct way to do this?



The code I used is:



beginequation 
L=frac12 m dotvecx^2
endequation


which give me

I'd probably do



documentclassarticle
usepackageamsmath
begindocument
beginequation
L=frac12 m Dotvecx^2
endequation
enddocument


enter image description here



because the Lagrange function is a function of the square of the time derivative of x (and not the time derivative of the square of x).

    At the beginning, amsmath provided capitalized versions of the math accent commands, which had to be used for “nested accents”. A later version of amsmath made the standard commands (all lowercase) “nesting aware”. The other commands remained for back compatibility.

The first or third option below may be close to what you're looking for. Or, switch from Newton-style to Leibniz-style notation for the derivative, as shown by the fourth option (newly fixed to incorporated @marmot's comment). A separate comment: to make the frac12 term less visually dominant, consider using tfrac instead of frac.

    I'm pretty sure Leibniz didn't use upright d's. ;-)
    – egreg
    Dec 7 at 8:52










  • @egreg - I'm pretty sure of that too... I switched to slanted to upright d's mainly on the (now deleted) suggestion of marmot. :-)
    – Mico
    Dec 7 at 10:25










  • @egreg That's a very bold statement. Did you know Leibniz personally? I would bet a lot of money on having him typeset the d's upright. Assume you have diameter $d$ that depends on time. How would you typeset its time derivative? fracdddt? Not really, right? And after all this is a question on the typesetting a physics Lagrange function, and at least in physics people won't hurt others' eyes by typesetting fracdddt.
    – marmot
    Dec 7 at 13:46










  • @marmot - Wouldn't it be nice to have access to a few first-edition originals -- facsimiles will do too, I suppose -- of Leibniz's own publications? (In case you're curious: I'm afraid I have no such access...)
    – Mico
    Dec 7 at 14:08










  • @Mico I guess we will not be able to figure out how Leibniz would have typeset it. However, I have a reason for pushing for upright d's, namely examples of the type fracdddt. Do you have examples in which upright d's lead to an unfortunate output?
