3U Maths Question Thread

Would I be able to trouble you and ask you to type up that thing on here and then just copy paste the code into a new post? That's quite difficult to comprehend I'm afraid...

Ill send you a pic of my solution to a q... but errr how do i upload pics on this i have an iphone lol

Try the ATARNotes app if you want (y)

is there an atar notes app now? omg lol

btw quick question: my 2u test next monday consists of year 12 trig, logs and exp and i have done most of the chapters on cambridge for these topics (ceebs application of differentiation and integration, trig graphing). So for this week should i practice hsc papers or syd grammar papers (yea i printed from 01-16).

Sure is - It's been around for a while!

Do the Trial Papers, save the HSC exams for closer to the real thing - And go back and do those chapters you missed!! Imagine how much you'll kick yourself if you forget something from one of them

Do a nice healthy mix from everything - Like, an area question with a trig function there, a volume question involving an exponential here, a tangent to a logarithm there - Just get some practice applying the knowledge to practical problems, even just a handful

Yeah I normally just start from development. I don't think extensions are necessary for 2u test right

Nah definitely not - Developments are plenty in that textbook

quick question, so in the 2014 hsc 2u multiple choice q7 i the number of solns  (sinx -1)(tanx + 2)=0 0<x<2pi i got C, which is 3. The ans on boardofstudies says B (2). However when i used graphing calculator i see 3 solutions. So, which is right??

Are you sure? I only see 2 x-intercepts

Please post up the question; I don't have access to the textbook! Rui might...
