    2024 Ext2 HSC Solutions to Q10 and Q16bii

    the way i did bii) was proving that \cos\left(\frac{2^{n+2}\pi}{9}\right) - \cos\left(\frac{2^{n-1}\pi}{9}\right) = 0 using sum to product formula surely i get the full marks right

    a=i b=j c=i is a counterexample im pre sure as the angle of a+b+c is smaller

    for ii) i proved like cos(2^n+2) pi/9) = cos(2^(n-1) pi/9) and just like recursively found my way to -1/8 hopefully thats right lol

    those equations will most likely not be examined as they are not accurate to "square" resistance

    are you going to be streaming your reaction to the test again this year?

    if u wanna do it just say above "let sinx = s and cosx = c" or equivalent just to be safe

    nope i believe thats under induction. it probably falls under this one but idk im not a syllabus slave never looked at this thing before tbh

    its a mix of proof an integration and im pretty sure its in cambridge

    tbh it probably wont show up, but given that there was something similar in the math adv hsc (2022 q29) i would just say give the question a go its not too bad

    if it does appear then it will probably be some squeeze theorem with riemann squares. usually the questions arent too hard tho

    wasnt q13 c last year an 8 marker projectile motion question? we probably will get one in q14 or 15 i reckon tho

    yea tru we more likely to get some complex bashing geometry question but if the exam markers are lazy they could totally just steal an inequality off aops lol

    we bouta get an imo inequality in q16
