Thread: \lim{} weirdness and \norm{} disfunctional

I just posted and found something weird. The 'limit' tag worked in preview, but then in post it changed the "h -> 0" to a subscript - not an underscript, namely:

The 'norm' tag does not work, so I used double vertical bars .

To get you have to use the \displaystyle command.

For me, even in the preview, I get subscripts for limits, not underscripts like I'd prefer.

For the norm, use \| (backslash vertical bar) to get .

[II] the norm:

backslash norm

vs

piped norm
