(is that a challenge?)

Oh yes please!

 

[asianese]

Haha trust nooblet94

I thought any theorem/technique should be allowed as long as you say what it is and use it correctly.

Pretty sure that if you want to use something outside the syllabus you have to derive it.

Yes because Taylor Series is part of the HSC...

umm its actually been in a few question 8's in 4unit over the years...
me and my cousin were doing this yesterday lol

If you can only see a method that you know that's not in the syllabus, just do it anyway but if there's a method that in the HSC, take the HSC method.

Yes, but you can't say sin(x) = *insert taylor series here* in the HSC exam, and then do stuff with it.

Why? Because Taylor Series as a topic is not part of what you learn. It's not in the syllabus.

um no shit.
the question will say... using the taylor series... or given that the taylor series is this and that...

 

[Riproot]

I am allowed to use alternate methods in school.

You read that wrong. I meant, if you don't have practice using another method, you'll probably fuck it up during the HSC exams.

Lol, I was just showing an alternative method.

Taylor series (and any series in fact -- including loan repayments) is my favourite topic in maths. Probably why I loved complex analysis in university (the last section involving residues is basically all taylor series).

Ah, right. I read it as you were saying if my school didn't allow alternate methods, then why should I expect to be allowed to use alternate methods in the HSC.

I know, that's why I said you read it wrong. Gosh.

 

[umm what]

wtf is the op tokin bout??
never heard of it

Never you mind. It's not in the Syllabus, but it's just an interesting Principle.

 

[Trebla]

The HSC questions are typically designed and worded in such a way that trying some approach outside the syllabus is far less efficient than using the methods within the syllabus. Also, generally if you intend to use a result that has not been covered in the syllabus, it is expected that you will derive it using only concepts within the scope of the syllabus (rather than quote it).
