I did a reverse proof thing for the identity question (I multiplied by the denominator, and then again) and managed to get the LHS. Do you think I'd be credited for this?


Yes, it doesnt matter whether you approach from LHS or RHS, as long as you prove it.

Asymptote for second graph was y=5, I think?


Naa. there is no asymptote becuase the unreflected parof the graph goes through y=5. an asymptote is where a curve does not intersent but gets closes to it so yh

You need A*'s in both C3 and C4 to get an A* overall :frown:


You need an average. Not 90 each. :smile:
WOW!! EASIEST PAPER EVER! AM I RIGHT GUYS?!?!

What was the co ordinates of A in the iteration question ?


(3.1, 13.9)

no. you're wrong lol


i got -4e^-4 which is around -0.7 and (1/8)e^-1 which is about 0.3 i think?

How many marks was the last question? I somehow missed the whole question out. FML!


quite a number of people missed the last one as well

It is an asymptote, and you still needed to draw and label it.

x - 3.something
y - 13.something

Was it a long question? It sounds at least 6-8 marks.

Same as you apart form number 9b and c

Yep, got the exact same answers as you! :smile: except for the f(x) for the cubic. I don't remember getting negatives

although for the last part of the last question, I differentiated again and showed that the second derivative is greater than 0, therefore it's a decreasing function

so...seems ill be redoing some maths exams next year, no way am i settling for my insurance choice just bc a paper killed me


I did that last year and it's honestly the best decision! The year goes so quickly you appreciate going to uni more you mature and you solidify your maths knowledge

So many of my friends rushed into clearing and hate their unis resitting honestly isn't as bad as everyone makes out x

so in june 2013 it was a*57 a 50 b 43 c 36 d 30 e 24

what do you guys think of this paper in comparison to june 13?


The june 2013 paper I guess was equally hard! Grade boundaries should be similar
An asymptote isn't necessarily something that it doesn't pass through - lines can intersect asymptotes so y=5 was still an asymptote as it tended towards that in the negative bit

oops, someone already said that!

extremely hard but think I've done well.
Will post a proof of the trig question in a bit if you want.
