What to do with the algebra-precalculus tag?

+2
−0

This question is prompted by a recent question with the tag algebra-precalculus, although I see that it's by no means the first.

This tag apparently means something to some people. I believe that specifically it means something to people who went through the US education system (whether in the US or in an American school elsewhere). But to me, as a product of the British education system, I look at the six questions which have the tag and four of them involve concepts or notation which I first encountered after differential and integral calculus, one of them appears to be really geometry and tagged algebra because it's an X-Y problem, and the less said about the final one the better.

I think we need to do one of three things with this tag:

  1. We delete it as unhelpful.
  2. Someone who knows what it means writes a detailed tag wiki for the benefit of those from other educational systems.
  3. We rename it to something which can be understood internationally.

I've placed those in what I consider to be ascending order of preference. Suggestions for point 3 are welcomed. Following Wikipedia, I would propose elementary-algebra.

Wikipedia has an explanation that is pretty similar to my understanding: https://en.m.wikipedia.org/wiki/Precalculus

In my experience, it generally consists of

-an introduction to trigonometry
-an introduction to proofs
-an introduction to (infinite) series and products, and limits

With the exception of https://math.codidact.com/posts/280118, (which IMO doesn't fit the tag), the others fall under the above three points

The main problems with the tag is of course that 1. It's vague (i gave three different topics that fall under it) and 2. It's more a grade-level designation than anything else - it's the thing students take between algebra and calculus, and in fact I'm pretty sure it's just called Algebra II in some places, so it's not really consistent.

I would say we delete it as being too vague, and re-tag questions as trig / analytic geo / infinite sums etc. as appropriate.
