2017 CSSA Maths Extension 2 Discussion

[jamonwindeyer]

Here's a space for you guys to discuss the 2017 CSSA 4U Exam! Were the questions kind? Did you study the right things? How would you change your approach for the real thing in October?

Papers were required to be held until today (Thursday 17th) so we can now chat about the questions and the approaches we took. However, please do not share copies of the exam or anything similar!

Please do not post the specific questions - Some students are yet to complete the paper and we want to keep it fair!

Had like 40 mins to do like 15 marks I skipped but I skipped like 10 marks in the end which I'm pretty sad about, didn't know how to do those questions...

For trial 3, going to study more hard questions.

Friend: "How'd you find the circle geo"
Other Friend: "By far the easiest one we've ever been asked"
Me: There was a Circle Geo queston?

Awesome to hear you know what let you down and that you already know how to fix it!! Literally the most important thing for these exams

I don't know anything about the test. Does anyone want to PM me questions?

We weren't allowed to take the paper back but I remember there was one question that I didn't know how to approach. It was like sketch: x^1/2 + y^1/2 = 1
and idk if you were meant to know how to draw it or if you were meant to use implicit differentiation.
Then a later part was something like :

(absx)^1/2 + (absy)^1/2 = 1 and i assume that means you can replicate the curve from the first part but in all 4 quadrants?

And yes, you need implicit differentiation to handle the original graph of \( x^{1/2}+y^{1/2}=1\)

Ah thank you, those transformations are handy to know.
