Apr 22 at 17:51	comment	added	Michael Hardy		When you write `\text{det} A` rather than `\det A` then you see $\text{det} A$ rather than $\det A.$ This doesn't just mean that `\det` provides horizontal spacing; rather the spacing depends on the context, so that `\det (A)` gives you $\det(A),$ with a smaller amount of space to the right. And this also applies to the left side. The same applies to using `\text{trace}` rather than `\operatorname{trace}`. And in `\operatorname*{argmin}`, the asterisk affects the formatting of the subscript when in a "displayed" (as opposed to "inline") context.
