thanks :oldsmile:

Hi just wondering if anyone had the hsc score to atar contribution graphs similar to these from 2022? https://drive.google.com/drive/folders/1zupPYCLi8EjbgULFMxoZP9DZ7iAHubxA Thanks in advance

anki flashcards: https://drive.google.com/file/d/1G7zO3RIlZpcB9BL5krF92N69X6S_Ad_7/view?usp=sharing dropped bio but I made these notes+flashcards for task 1 so maybe someone will find these useful :) download the document and then it'll take you to a docs link cause my zip file/pdf is somehow...

maybe drop legal? the scaling is kinda bad lol, what subject are you picking up?

Yeah I like started from -i and then I drew a line from it to -2 to find √5 (which looks sorta off) and then for max value I did -i to 2i = 3 but that seems insanely wrong💀

I ended up w/ this but I'm not sure if it's right and then part iii was to determine the min value of |z+i| which I don't get as well

um I don't think the q. says anything?

I don't get how to graph the left one and find the region for this q. Thanks in advance

okk cool thanks, how would you do part ii then?

I've converted 1+i and 1-i into mod-arg form and subbed the n in but I don't know how to get the RHS as well as part ii. Thanks in advance

ah ok thanks I forgot to scale it so my answer was off, thanks!

Answers say that B = -1/2 + 5/2i D = 9/2 + 1/2i but I don't know how to get there Thanks in advance

Hi does anyone have the 2023 cssa math adv paper by any chance?
