ngl that whole paper was difficult excluding q11,12.... i just got within the e4 range

 

[SB257426]

the matrix solution is better imo

just did this paper (haven’t marked yet but I assume this isn’t how the solutions do it), but the way I did it was to create a vector r defined as the projection of u perpendicular to v, and hence r+p=u, which you can sub in, and then from here the proof is pretty trivial

bruh your jk surely?
did you get 70/70?

 

[carrotsss]

did you get 70/70?

haven’t marked yet, I’ll tell you once I do

nope, only 68

 

[synthesisFR]

nope, only 68

Only

 

[carrotsss]

Only

I mean it’s less than 70 and he said 70

 

[synthesisFR]

it’s ok ur just bad
Im gonna do the paper now and beat u I will update in two hours

me when i just started the paper

 

[scaryshark09]

nope, only 68

that was first in the state last year (99 aligned) lmao

bro this is literally fate, carrots is state ranking maths
anyways @carrotsss i hope u beat all the tutored city bastards and get 1st for mx1 and mx2 god bless

mx2 i dont think he can if he got low 90s raw. but mx1 theres a chance. hes got insane atar contributions from them regardless
