why is 3 c?
MC 2 was the inverse function, which is reflected about the line y=x, so it would have to be d) not b)qn 2 is b isnt it?
You had to take the AOC reflex angle to satisfy the rule that AOC=2*ABCwhy is 3 c?
I had the exact same. Let's hope that they're all right.1) c
2) d
3) c
4) d
5) a
6) a
7) a
8) d
9) b
10) c
It's 100% + 1st internally + good 2U or 4U marks usually.6 is B, asked someone who would be close to a state rank. It's 100% = state rank for 3u right?
no thats not what it says, i just checked. i think your wrote one of the cases. on the line below it has the thing with (-1)^mCambridge 3U year 12, page 33:
"The general solution of is "
Divide by 2 gets A doesn't it?
After a massive discussion, it's definitely B lol.6 is a
Its definitely B. Check any textbook. If it says A then burn that textbook.After a massive discussion, it's definitely B lol.
lol i didnt know the general solution for sin. i suspected it was B, and i confirmed it by testing for n=0, n=1, etc. not that hard to do as long as you understand sin is positive in 1st and 2nd quadrants.Its definitely B. Check any textbook. If it says A then burn that textbook.
In my opinion its a bad question. ROTE learners galore.
