bro necroposter kinda late but do math advanced and math extension 1 for prelim and drop down if you need

yo we go way back

1+i=√2cisπ/4 1-i = √2cis(-π/4) (√2cisπ/4)^n+(√2cis(-π/4))^n = √2^n (cis(nπ/4)+cis(-nπ/4)) =2(√2)^n cos(nπ/4) QED as req blah blah blah for part ii do as cossine said (use binomial expansion) and see what happens

Wake up at 6, study until 12, eat lunch until 12:10, study until 6, eat dinner until 6:10, shower until 6:20, study until 12am, sleep (lucid dream so you can study inside your sleep)

You could try a telescoping sum and see what happens

How about for a ‘show this’ question (like 14ci 2023)

Do what you enjoy I think physics is a more interesting and enjoyable subject than biology but not everyone shares the same sentiment

Mx1 and mx2 are each 2 units if you take mx2 If you take only mx1 and advanced, mx1 is 1 unit

Mathematics Extension 1 Mathematics Extension 2 Chemistry Physics English Advanced

I don’t think many people going into med take bio for that reason Chemistry on the other hand seems to be a prerequisite or at least good to know at some universities Scales pretty well Personally I would’ve thought physics + mx2 would help with engineering more

Plz gimme

If you don’t study you'll fail and work at maccas for your whole life until you die

I’m not entirely sure if that method gives full marks but I used a right angled triangle to find sin using cos and got 3/3 for it.

it doesn't ahve to be u just need a general idea of what ur looking for may i ask how you're expected to find these values also i'm not sure but i feel like the question might want some exact bounds

calculus ig idk
