Induction Inequality

If we avoid discussing stuff external to the course on here we do foster an unnecessarily inward looking perspective. Remember I did provide the disclaimer of "this is supposed to be done with induction".
Also, in vic at least I was under the impression you can put down whatever is correct... providing you explain it properly (unless of course it specifies a method).

In the HSC the same goes, but you won't get marks for working if your answer is incorrect. So if you happen to make a small algebraic error you've lost all the marks. It's a bit of a shame really; I like seeing new methods that work and they lose out because of a sign error! :P

Trust me. If the HSC is against L'Hopital's rule, they'll be against anything
(Unless the new 'method' is just a new way of applying techniques taught in the course)

Usually in the cases where an abstract method is used - Provided it is reasonable and correct, it gets the marks. Not sure why L'Hopital's causes such trouble :P

It used to be fine; L'Hopital's was mentioned and not frowned upon explicitly in the notes from the marking centre.
It's a seemingly recent trend; only came about like 3 years or so ago. Maybe a bit more though. But basically the questions that the exam-writers made were not made for a "tactic" or something outside the scope of the syllabus to be used. Exam writers have to think about what an MX2 student is supposed to do and write questions accordingly; using something like L'H sorta defeats the purpose. Mainly cause they want to assess your understanding of the course you were given, not necessarily your own skills
If they can't pay L'Hopital's rule, I can't see them paying modulo arithmetic either really.
(Not that I approve of it either tbh. But things are just the way they are. Stupid HSC)
SpoilerIt's also a part of why I looked forward to maths at uni back then. Get out of these constraints :P

Eh, not that it matters because they'll request induction anyway :P
