Methods Exams 2014: Predictions

[Yacoubb]

Agreed- tan graph would throw a lot off

Especially since it's really uncommon!! So better prepare for it, haha!!

Haha do you mean something like VCAA 2009 Exam 1, Question 4 or VCAA 2008 Exam 2, Question 4?
Looking at the examiner's report, it doesn't look like a question that will completely catch people off guard (about a third are getting full marks for the Exam 2 one or around 50% for at least one mark per question in Exam 2) so it's not really a 'killer' type of question you'd expect but definitely possible that it'll come up no doubt!

Best be prepared for anything
& I don't mean solving for x. I mean actually sketching tan graphs.

Ah yeah that makes much more sense LOL (that would knock quite a few people off actually)..

Yeah, it's SO uncommon, and a lot of people don't really think about practicing for it. It's definitely something to be wary of.

The way I tackle sketching circular functions is finding all x intercepts, asymptotes, turning points etc. For a tan graph, finding when cos=0 will give asymptotes right?

Yup (take into account transformations though )

Hey i was curious how much would i need to get on exam 1 and exam 2 to get 25 plus study score with a medium-strong cohort with a low ranking 50-60% in my sacs?

Thanks in advance

I wouldn't personally state the turning points unless asked to & as aforementioned, account for transformations.

[Sayf44]

Ok thanks speedy and yacoubb

Turning points are important points and must be stated in any graph of a function.

What? I've never come across a question that by default needs that, and if needed, will mention, label TPs and x- and y-intercepts... oh well, I'll start putting them in from now on in.

[GeniDoi]

Best of luck tomorrow everyone!

For weird graphs (like cubics/quartics), probably just do the stationary points last just in case (also because they take a while). However, that's what I was ALWAYS told by my methods teacher (I heard it once a week)

[ChazRose]

Any specific predictions for tomorrow afternoon?
