    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.

      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.

    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

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

    lim x->0 1/x

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

      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.

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