8 was B

8 was B

no it wasn't it was c, check values inside and outside of the region and u will find that b does not work

 

[bananapoggers]

I just fully expanded the LHS and RHS separately (like LHS=… RHS=…) which then showed that LHS=RHS

yeah brute force it

bro i tried all options c is not right, im pretty sure you get like the radius being larger than a point on the circle from z=0 ( i might be wrong dont know tbh seeing i didnt even get the double angle out for 15 ii lol)

Isn't the circle generated by B in the wrong quadrant? Maybe my cartesian expansion had an error, it looked wrong so i went D

nah just did it again, i used i and another number cant remember, also a and d are disprove by subbing in i and then b is wrong by subbing in a point in the shaded region

um basically i subbed z=2.5i and z=1 and i got b

crap then in that case yea its not b

What u guys think will be the cut off for E4 this time, 2022 was 61.

i feel like this test was a bit easier then 2022.

thats what i got

 

[Hudz777]

no way I got 10/10 mc by an educated guess (I had no clue for any). “ahh yeah, acc decreasing, must mean a.v is decreasing”. Free CHICKEN dude

 

[Hudz777]

oh yeah, 8 is definitely D

from you guys haha - “the general consensus”

 

[SMARTYPANTS_SINGH]

they didn't, but they have a copy of the exam so they just worked it out "together"

Wait was 4U this year harder or easier than last year?
