hmmm idk i stayed a bit afterwards and then went off with carrot and two others?

Tall guy with glasses?

that's me lol

no the other one

I found Q12 (e) very hard
Had no clue how to even start :S

 

[Sy123]

Here are solutions for Q14, also part (c) is exactly the same as a recent 4U marathon question by coincidence

Part (iii) the 'average' is part c last part of Carrot's paper

Find an expression for the volume lost in each container

Differentiate each one.

Put them over each other and it simplifies easily.

Holy crap that was such an easy examination.

 

[SpiralFlex]

Holy crap that was such an easy examination.

I would call it reasonable, perhaps people doing only 3U may feel unease toward some questions.

For some reason i felt like i spent half the exam on Q12. I think it was the fact that it spanned over so many pages. Every time i thought i was nearing the end of it, it said "question 12 continues on page..."

 

[HAX0R]

I only made 40 sillies. Forgot to answer the questions.

Not sure if troll or really in Year 7

Coincidence? Ha I think not.






Hahahahahaha I'm such a beast at these puns omg

I'm curious to know this too actually.

I was like 'wtf' when I got up to the Q13 Projectile motion question. Got stuck on the limiting population of the pigeons and I skipped quite a few questions due to time urgh.

For some reason i felt like i spent half the exam on Q12. I think it was the fact that it spanned over so many pages. Every time i thought i was nearing the end of it, it said "question 12 continues on page..."

I thought exactly the same thing, e.g. the circle geo diagram took up a whole page and was only worth 2 marks lol. I swear the average marks per page in that question was 3.

Also, I can't believe I didn't just sub in values or used L'hopital's rule for the second MC, I did the long 'standard' way of algebraically manipulating it oops

 

[Carrotsticks]

The proper way you mean? That's the spirit!

 

[fishrushed]

I went back over the paper after (spent another 2 hours on it) and I still couldn't figure the projectile, the last binomial and the birds question

I felt that too D:
Every question seemed so long, felt like a paper full of conics LOL
Talking of conics, I can't imagine what the 4u paper will be like

btw, was it just me or was this paper harder than last year's?

 

[Makematics]

Hint: Use the Quotient Rule on f and g.

sooo what was the answer? i still dont get why A and D arent the same thing :/

C (from memory -cbb flicking back)

 

[Makematics]

C (from memory -cbb flicking back)

ok but B and C are the same thing too...

Wut no, look carefully at the inequality signs and the derivative.
