*juz re-posted the ans, spotted some typo error ;
if u see any more, pls let me know/
sorry to keep u waiting...
was converting txt to img
i also give u the extras in case u encounter min, instead of max. or vice versa in the future.
btw, the other tutor's post, he misread the qn part (iv)
hope this helps.

Oh I think I finally get it, thanks for the expln and gg the extra mile to help me :) I haven’t been paying attention in class so this helps a lot lol.
nah, not ur fault.
this qn is a HOTS qn.
even if u hv paid attention,
the addition of 42 and Rsin(θ + α) PLUS the reciprocal is enough to make even me confused and i also made a few corrections for the post here. lolz

u dun see no more typo??? :)
ur ans for iv in is wrong tho, min is positive 1/68963 in ans sheet, dk how that makes sense
Lolz ya but I think i kinda got the hang of amath
thanks! let me double check with graphing calculator
meanwhile, do u mind replying to Ck's new post? (it's alright if u hv no time to do it)
it's on R formula too. :)

Ah ok id try
okay, i hv double check using graphing calculator.
The max. and min values of [41sin(2θ+12.7°)]³ are +68 921 & -68 921
do u realise +1/68963 is my max value in (iv)?
between +1/68963 & -1/68879, which one is the smaller value?
dun make sense to me if +1/68963 is the min value.
maybe u can check with ur teacher?

Sorry I tried to do her qns for 30 mins but futile effort. Im trying still ya.
Yea I agree with u, doesn’t make sense 2 me oso.

Wait I js read ur comment I think I know how I’d answer
i know Ck's qn wld b a good practice for u.
din noe Ck is she.
ohya, i finally m able to prove:
tan(90°+2θ) = -cot2θ
so thanks to u , i learnt something new lolz

erhmm,... u shld ask ur sch teacher even though u r afraid of her.
if the ans sheet is wrong (typo maybe), and not corrected for, can u imagine countless of stdnts after ur batch wld still b confused?
jus saying,... lol

and thanks for ur upvote too! :)
eh yes omg I was thinking abt the proving last night, then I did it in the morning forgot to show u lol but that is the only one that’s true. The rest can’t js anyhow change the sign.
Hahaha rmb when I said I owed her homework? I think she’s still hopping mad over it. Id Wait 4 her to cool down 1st when sch reopens. But then I’d probably forget abt it by then lol. So I’d js ask another person lol
