Does anyone have any tips/tricks for 2U maths trig identity simplifying?
one of the tips my maths teacher gave me is to try to simplify/expand the trig identities on the right hand side of the equation as well, because it makes it easier to equate both sides :)

should i go to peak chemistry for year12 if roy fu isn’t my teacher - his classes are full rn. i finished the yr11 syllabus with matrix online but don’t wanna do that for year 12.

my options are zhangs, ace and peak - but i’ve heard zhangs has really unorganised resources/notes but idk how much of a difference this would make if the questions and teachers are good.

thank you 🙏

does anyone know a good piece of poetry to use for a related text for Othello, specifically related to being 'the other'/being an outsider?

100% i think you should book a trial class in whatever class is available and see if your teacher is engaging

I have recently been given an assessment notification for 2u maths. It's an 'investigation-style examination' covering preliminary trigonometry concepts. My teacher says it's an open book, which has caused me to dread the exam because that means that the maths department has an excuse to make it especially tricky! Should I be worried or am I just being irrational? Surely the test couldn't be too hard in the interest in the class not having a dreadful average mark. Furthermore, what topics in trigonometry can render the most difficult/ band 6 questions and how should I prepare to cover any and all possibilities to ensure I get 85% or higher? Thank you. (It's in two weeks).

no. THey are usually rlly simple. The thing that might fk you over is the actual assignment. Note that this component marks like a b.

omds same mines a cheat sheet exam and they gave us 4 weeks notice when they normally only give us 2 so im just wondering how hard it could really be, but i think practice more problem solving questions rather than textbook style because if its open book itll most likely be applications of trig on like unseen questions so just do as many past papers as possible to avoid seeing unseen questions for the first time

Hey all,

For an investigating science depth study, I have to survey society (as many as possible) on the belief that extraterrestrial life exists given the current evidence and the vastness of the universe.

It would mean the most if you could please complete the following survey: https://forms.gle/vB4vjE6q4JPMCbva8 . It only takes 5 minutes tops.

Thanks to everybody in advance!

it shouldn't be that bad ngl, but be careful and try to get full marks on your hand in or open book thingy. often the exam ranges from easy to medium difficulty but the assignment is marked very precisely, any little mistakes and they usually tear you to shreds on it. in math exams as long as your general process and answer is right and you use a few shortcuts here and there you'll get the marks but for assignments you don't have that luxury. just be careful and show ALL working. doing this will also help you understand batter and help for your exam.

in terms of concepts hsc trig itself doesnt get too hard so prelim will be okay. key concepts are radians and converting to and from radians and degrees, unit circle, reciprocal identities, pythagorean identities. common question types are solving eq's, proving stuff, applications questions with a bunch of words, and questions where they give you one of the 3 main trig thingies and ask you to find the others (e.g sinx=3/5 , pi>x>pi/2, find exact value of secx and tanx)

good luck!
