Cosine and sine rule discussion. In the course or not?

[Special At Specialist]

I never started this topic.

[LOLs99]

Maybe Calculus, Vector Calculus, Mechanics...that's it I think

You won't need the sine rule, cosine rule, circle theorems or sequence and series (which is everything from 1C to 1E). Pretty much anything else in the textbook you do need, though.

Um, you will need the sine rule and the cosine rule...
And I would recommend remembering some of the basic circle theorems, you never know, it could come in handy

Not for methods/specialist. Only for futher maths.

He's done Spesh though,  wouldn't he know if you need to know if we need sine / cosine rule!?

I was reading through the essentials specialist book and was wondering which chapters were absolutely essential? (Get it?)

That's terrible...

It always helps to know the sine and cosine rules, comes handy in some vector proofs and you use Lami's Theorem (essentially the sine rule) in statics.

Hey, How is my joke terrible?

But thanks for the replies.

Dude, if you're doing lami's theorem, you will need to know it
Plus, they are both on the formula sheet, so you NEED to know how to apply them, just like the alternate rule for finding the area of a triangle
You will need to understand and know how to apply every formula on that formula sheet

Okay maybe the sine rule, but not the cosine rule unless you're doing either physics or further maths.

Dude, it's not hard to 'learn' the sine and cosine rule. Sine rule is just simple a/SinA = b/SinB = c/SinC and cosine rule ( see attached ).
I've found these to be handy with some vector questions that I did in GMA and probs in spesh as well.

[Mr. Study]

Thanks for all the replies!

It does help to have a little discussion, as it clarifies A LOT.

if you're really determined to get a score of 50 in spec as you state in your sig,I think you should take advantage of the fact that ex-Spec students are saying you need to know it! since the SINE and COSINE rules are probably either assumed knowledge or things that would be required for topics covered in spec! or maybe, .. things that differentiate the 49 from the 50?

Well to be honest it only takes like 1 hour to learn. And you could argue also that everyone in specialist should start learning similar triangles and area/volumes of all 2D and 3D shapes, since they have even more of a chance of being in the exam.
I'm just saying, as far as the textbook is concerned, the cosine rule is one of the least important matters. There are more important things outside of the textbook than that. But I agree, it's so quick and easy to learn that there's really nothing to lose by learning it.

I learnt the cosine rule last year and found it very easy. But just because it's easy doesn't necessarily make it relevant to the course.
Look over the past 5 VCAA exams for specialist maths and you will find that the cosine rule is not used at all on any questions.

lol give it up mate
I'm pretty sure there was one question in the multiple choice section that required the cosine rule on this year's exam paper (it was vector related), or maybe I'm confusing it with a question on one of the trial exams I did
Plus, if you're using Lami's theorem, the sine rule isn't enough
and no, you don't need to memorise every single formula for the volume and areas of certain shapes - they give you these formulas, just like they give you the sine and cosine formulas on the formula sheet
If there is something on the formula sheet, you would be an idiot to not go over it and understand it well enough to be able to apply it

and fyi, you do need to know similar triangles for methods and spesh for some of the questions in the related rates section...
