I'm trying to write a dot over a subscript - like
f_{\dot{x}}
My problem is that this comes out looking all wrong. The dot is inside the x, it's just messy. Does anyone know of a way to do this?
P.S I'm doing this because I want to write the euler-lagrange equations in the more compact form
f_{x}=\dot{f_{\dot{x}}}
so I need a method that will accompany another dot on top of the one in the subscript. Any help would be appreciated.
Edit: Mico answered this below to all who have the same issue! Thanks Mico!
f^{}_{\dot{x}}
, with a dummy superscript. It's unclear what you want to achieve withf_{x}=\dot{f_{\dot{x}}}
: can you show an approximate representation or point to some image?amsmath
package? Please confirm.
