Can there be perms and combs in ext 2 papers?

[scaryshark09]

^ if so, how common? and can you give some examples?

like i mean can it be included in anything like proof or induction?

cause perms and combs arent in my ext 1 trial cause some ext 1 classes haven't learn yet and i was wondering if there is any point learning for ext 2

Perms and Combs will likely be in your 3U Hsc either way. You'll have to learn it at some point. Dont think it comes in 4U, i might be mistaken. Binomials may come up for proofs etc, i reckon.

Ps and Cs are not in Ext. 2 under the new syllabus. The only slim possibilities I can imagine are using pigeonhole principle in a proof and understanding what a factorial is.

Technically yes but I highly doubt it.

If they do everyone gonna boycott the hsc and Australia is going to fail as a nation

It’s like how after hsc or trials ppl start hunting down the authors of the comprehension paper texts which they didn’t understand LMaoo
This happened in my school during prelims

It's gonna be a repeat of the "lets jump into the pit of distance d" projectile motion question from last year MX1 HSC

tbh that wasn't that bad tho.. it was just an easy collision question
the hard part would just be to recognise the max value of the trig thing but overall it would be easy to get atleast 3/4 marks which is good for a q14

I don't even want to think about that question again - never had I seen a question with a moving target before

tbh it was last year so I can't remember too well

its projectile motion so it is moving
its just simultaneious eqn for the two motions

Look - back in the day (one year ago ) I had no clue what I was doing and I am now glad to be done with MX1

damn thats so lucky tho u have so much time for everything else

Yeah I'm taking 12 units, but my timetable only has 9 units since some of math is done - plus one of my subjects is an online course (Software taken through a different school because our teacher left - woohoo) so the timetable is quite empty with frees.

Still feel like I'm dying in English adv though

relax mr 99.8
bro was in y11

altho the q14 vectors looks disgusting
i kinda already spoiled the paper for myself but im trying to forget it so i can do it before the hsc

Now I'm gonna feel bad I seriously found it difficult day of

Literally it doesn't matter if you've seen it before - I stg everyone is like "oh no I've seen a question before now I can never do it again!" - come on, it's fine

My schools auto & engineering teacher is leaving and the school is just straight up forcing the year 11s doing those subjects to drop, consider yourself lucky
