Whatever LaTeX does by default

[-] PM_ME_VINTAGE_30S@lemmy.sdf.org 54 points 2 years ago

LaTeX: typically let software decide for me, override if it looks bad.

Paper: Too shit at writing to make a consistent choice

[-] TheFriendlyDickhead@lemm.ee 25 points 2 years ago

B. A only when there is little space

[-] hihi24522@lemm.ee 7 points 2 years ago

Same, but there is never enough space

[-] smeg@feddit.uk 6 points 2 years ago

Same. B if I'm feeling fancy, A if I'm trying to fit everything on one line.

[-] Tja@programming.dev 15 points 2 years ago

Are those called limits in English? How do you call those things then?

lim x->0 1/x

[-] PM_ME_VINTAGE_30S@lemmy.sdf.org 22 points 2 years ago

For integrals, we would say that "b and a are the limits of integration".

The notation "lim x->0 1/x" would be read as "the limit of 1 over x as x goes to zero." In general, "lim" is short for "limit" of whatever follows it, with respect to what is below the "lim" symbol. Rarely, I have also seen the notation "l.i.m." used for the limit in mean, i.e. the limit with respect to the L^2 norm.

I’ve always called them the bounds of integration but I’ve heard the term limits of integration too

[-] Venator@lemmy.nz 3 points 2 years ago* (last edited 2 years ago)

Also limits. But also "tends towards".

[-] howrar@lemmy.ca 13 points 2 years ago

Better question: Where do you put the dx?

[-] Mubelotix@jlai.lu 6 points 2 years ago

What? Where else would you put it?

[-] HeyThisIsntTheYMCA@lemmy.world 9 points 2 years ago

Wherever you want it baby

[-] qjkxbmwvz@startrek.website 5 points 2 years ago

Immediately after the integral symbol, before the integrand, is also common: https://math.stackexchange.com/questions/1146345/notational-position-of-dx-in-integral

It has a nice "operator" look this way.

[-] Mubelotix@jlai.lu 1 points 2 years ago

I would interpret this completely differently than what was intended

[-] Car@lemmy.dbzer0.com 11 points 2 years ago

A fits on paper much better than B, especially when you try to write as small as possible to fit all of your work on one line

Depends on if the integral is integrated in the text or if it gets its own area

[-] chonglibloodsport@lemmy.world 8 points 2 years ago

The kerning on Latex integrals has always bothered me. The f(x) could move a LOT further to the left!

[-] lugal@sopuli.xyz 8 points 2 years ago

Know your limit

[-] Zagorath@aussie.zone 8 points 2 years ago

Out of these? I'm team Blue.

But really, I'm team Green. b goes more or less in the place Red shows it (or maybe halfway between where Red and Blue show it), but a goes to the left of the integration symbol, mirroring where the b goes relative to the curve at the end of the ∫

(a, b) at the bottom. It's a 1d integral, so nothing goes after f as well for me.

[-] PM_ME_VINTAGE_30S@lemmy.sdf.org 2 points 2 years ago* (last edited 2 years ago)

Best answer, although I work with delta "functions" a lot so I actually have to be careful picking which interval with boundary {a,b} to pick (for example, if I integrated δ(t-a)+δ(t-b) over all t in (a,b), I'd get 0, but if I integrated those deltas over (a,b] I'd get 1, and integrating over [a,b] would give 2).

Also I do have to do integrals with parameters and multiple variables so I can't really leave out the differential.

[-] oxideseven@lemmy.ca 6 points 2 years ago

a sits on the dooblydoo on the left, b hangs from the dooblydoo on the right.

[-] Feathercrown@lemmy.world 6 points 2 years ago

A, B takes too much space

[-] hexaflexagonbear@hexbear.net 6 points 2 years ago

Whatever latex does for me ¯\_(ツ)_/¯

[-] model_tar_gz@lemmy.world 6 points 2 years ago* (last edited 2 years ago)

+ C: I’m so indefinite, I don’t respect limits.

[-] sharkfucker420@lemmy.ml 4 points 2 years ago

Depends on if I accidentally wrote the function too large

[-] collapse_already@lemmy.ml 3 points 2 years ago

A gang. Does that mean I am old?

[-] jmcr@lemmy.ml 2 points 2 years ago* (last edited 2 years ago)
[-] rustyfish@lemmy.world 1 points 2 years ago

Always A. Except when I’m drunk.

[-] Iron_Lynx@lemmy.world 1 points 2 years ago

If a and b are simply numbers or variables (ex. 1, 2π, x), either, maybe red.

If a or b is a function (ex. (x + y), (1/N), (z - r²)), then blue.
