Trig identity + logarithm questions (2 Viewers)

[jane1820]

Does anyone have any EXTREMELY hard trig identity and logarithm (ritcher scale, solve this, N(0) typa questions)???

all the ones i find on thsc and google are like basic and none of them are HARD
(also for trig no radians plz - arent in the exam)

 

[Hehehe22]

Is this the kind of stuff you're looking for? They're not that hard though. There are some hard questions in chapter 8G enrichment section of the cambridge y11 3U maths textbook

already did the new senior ones and the cambridge ones but yh thats what im looking for
ill have to see if ive done the enrichment ones tho (dont think so)

Yeah the enrichment ones are pretty hard. I thought I had some worksheets but I can't find them. If ur confident with all the new senior and cambridge ones then u should be fine for the exam

do you knew where i can find hard trig identities? ive done the mastering math, new senior maths and picked out the cambridge ones
i sometimes lag and find it hard to figure out 'the next step'

Um yeah I wasn't rlly sure what kinds of questions u were referring to, bc trig identities become integrated into the other topics and in further trig proofs etc. It's just something that u have to know very well. Do u mean adv or ext trig identities? Cause there aren't that many in adv

advanced,
im looking for the ones that are like 'show that (sec+tan)^2=1+sin/1-sin' but harder bc these are pretty easy

Yeah soz I don't have any, but u can try sifting through some adv HSC papers for trig identity proofs

With maths adv I think this is as far as they could go(unless your teacher put in some ext1 level stuff in the 2u paper which could actually happen in school assessments)
