Dang it, think I messed up with some sillies. What do you think a 94% would align to?

Predictions for E4 cutoff?

I admit this paper was more doable than previous years. However, I definitely didnt perform the best I could today. :( I'm sad because i prepared hard for 3U for the past 2 years too...
Maybe 50/70, I really don't know. I'm Disappointed.

For the Rcos(x- alpha) did you guys get tan^-1(sqrt6/sqrt2) and did you leave it like that when subbing back into the Rcos(x-alpha)?

It’s alright man, same thing happened with 4u for me. Completely bombed 13 out, somehow did most of 16 but missed out on early marks. It’ll get better from here 👍

But the domain for f(x) was x>=1 so wouldn’t the range for f-1(x) have been f(x)>=1?
