For 2023 Q16 b i), how valid is it to swap x>lnx to e^x>x then prove the boundary is greater and derivative is always greater.
Only unsure because technically the later inequality is true for e^x>=x so its sort of a different proof by that logic
sorry don't know if this is the best place to ask but I feel like someone else may benefit maybe

nesa messed up with the alignment in 2020. bad alignment like 2020 is extremely unfair, because a 90 raw in math advanced doesn't even compare to a 50 in extension 2.
Yeah that alignment was a bit cooked- 77-79 to e4 is crazy work

@coolcat6778 Can we use L'Hôpital's rule to solve limits in ext math or not?
depends on the marker really, sometimes u could get marks if the marker isn't a retard.

the only place where they should deduct marks for using hopital is when it says to use their method

i don't see why they would deduct marks otherwise, as L' Hopital is an actual rule

Is it less likely they're gonna put some vector bs in the test cause there was so much of it in the last few papers.

Also how hard/strange does everyone reckon complex will be?
