Are limits allowed?
I've seen lately a bunch of questions about derivatives. I think it's fairly obvious that derivatives are a topic that uses calculus, but maybe there is some confusion. Please do not post questions about derivatives, integrals, or anything else related to calculus in this forum. That belongs in the university forums, specifically the Calculus forum.
If you have a question about basic simplification, solving quadratic equations, graphing in the xy-plane, etc. it should go in the Algebra forum above this one. There is no concrete list of Pre-Calc concepts so there is overlap naturally, but as a general rule post here only if you are in a Pre-Calculus class or in a Calculus class reviewing, but haven't gotten to any Calculus concepts yet.
If any one else has noticed a common error where a certain topic is incorrectly being placed in this forum, please add on to this thread.
Limits that can be done without using calculus (that is, using purely algebraic teachniques) belong in pre-calculus.
Limits requiring knowledge of calulus (eg. requiring power series or l'Hopital's Rule) obviously belong in calculus.
It's usually pretty clear.
The problem is that many students learn calculus in Highschool and think that posting in the Calculus subforum is only for university .... These students need to overcome this bias and understand the big picture.
I'm highly confused about the system. I have many non-universtiy questions that are calculus but not at a university level. For now i've been posting them in the pre-calculus section although I now realise i was technically incorrect to do this.
So I think maybe their should be a non-university calculus section maybe?
Which is correct for the following?
-Series/Proofs
-Complex Numbers
-Polar Co-ordinates
I tend to just stick with pre-algebra and algebra. I don't really understand what belongs in this forum. With the english education system, "after trig but before calc" means nothing at all. We don't learn things in that order. Is that even what it's referring to? I've never really understood it. I'm probably being naive; it could be an international thing, but it's that which confuses me. I don't see what it defined as being "after trig", for example.
I'm afraid I'd have to agree that it's confusing for new-comers like me, especially an English one because there is no concept of "before calcuuls and after trig" in the UK as has already been said. Neither is there such a thing as a "Calculus class" a "Pre-calculus class" or any class other than "Maths" (plural, of course!) Or if you're lucky "Pure Maths" and "Applied Maths" or "Stats" or "Mechs" or "Decision"
And I'll also agree that even as a pupil with only 5 days left of school before Uni, posting in the University forum would be far too scary.
Surely there could be a Calculus section for school?
