16 hrs to go i still dont know how to do inclined planes

100 marks just on proofs watch

and u can do complex number calculations idk if 100 has i

no just simple stuff, just makes life 1% easier so u don't make stupid algebra mistakes

i have a feeling the paper bout to be horrific

I think 99.9% of ppl sitting tmrs 4u exam have it boss

actually i saw a paper that had sum similar q15 3 marks

don't stress its one mark mc question at best

u = a-x sub

im on my knees for an e4 currently

brother ur getting high 80s I'm lucky if I touch 70s

im prob very wrong but for ii could u use one of the points on either line, and have the difference of direction vectors be the resultant direction? or have any point on both lines and just have that difference as the direction vector?

also out of the papers u have done, which one have u found challenging? i need to go to sleep crying and suffering

on which part? finding the line or co-planarity (is that even a word)

nah it was in my school trials, u basically let some parameter equal each of the components, so for x => 2a+2 then u get ur vector line, and show direction vectors are parallel which implies same plane

high 80s... r we doing the same papers bruh

a lot of the times there are free 3ish marks on 16 for like subbing in numbers so don't just not even look at it but yh I leave some of it unattempted id rather make sure I didn't do anything stupid on 11-13 and do some harder 14-15 then just waste and prob still get 0 for 16

is projectile with k components possible to come? I've tried to find it but it just doesn't exist on any hsc paper but I've seen a few on trials

i accept my fate to maths, who wants an e4 anyway?

occasional mark drops at 12 as well and if the day is not good 11 also happens
