How can I improve brakets in this equation please?



beginequationlabelE
E_0^(1) = expvalfrace'^2vecr_1-vecr_2Phi
endequation


enter image description here



EDIT:
And please, what is wrong here? I think that in the end should be Phi , but it is mistake by compilation.

    left...right? P.S. I usually write vecr_1 because of space.

    Please provide a compilable example. Where does the expval command come from?

    Off-topic: One should probably write vecr_1 instead of vecr_1, and vecr_2 instead of vecr_2.

    Instead of editing an existing query to pose what's essentially a new question, you should post a new query.

If you're using the physics package, then it looks like you have to pass two * arguments to expval to allow it to auto-resize the brackets.



As for your second equation, it is missing an argument. You had expval**stuff Phi, but you need to provide another argument: expval**stuffPhi.

  • You should definitely remove the double-backslash stuff at the end of the equation environments. Also, the limits directives are redundant; all they do is create code clutter.
