it was hard at first
then it got easier

i couldnt solve the identity question...cause of the exam stress though..but i however managed to do the rest and i am pretty sure most of them are correct

all you had to do is just change cot x into cos 2x/sin 2x
then just combine cos 2x/sin 2x and 1/sin 2x
you`ll get the answer...pretty easily done...
but oh well..

yeah it was a resit cause i had a 78 last time
and i wanted to make it a 90 just in case if i screw up on p3

what did you mean by the whole question?
the first part was really easy
they said

Sec 2X
then you have to use
1/Cos2X
1/1-2Sin²X
put the value of sin x in to that and just calculate

The whole exam!

by the way, what was trhe exapnsion in the Expansion Quetion? and WTF is the independent value?

i cant remember the expasnsion
i just know theres an x^36 in the front
and a 55/2 somewhere...or was it something bigger?
cant remember...

and when they said independent
it was meant to say that there is no x term beside the coeeficient

calculate it out
it should be quite small...in fractions id guess

NM screw it... RESIT HERE WE COME..

dont worry,im sure the commonwealth wouldnt do very well this time
11. I must say that P2 didnt go too bad for a first time (and only )

I screwed up on question 2b where you had to prove the identity, well maybe if im lucky the examiner will find some marks on the page where I randomly wrote down stuff which then led to = cotx

What did the graph look like in the last question? I just got confused with the modulus of it

Anyways, hopefully this P2 will make up for the terrible P3

How did you do ?
I thought that was a bit nasty... maybe not on the same nastiness level as the P3, but still a bit evil

Did anyone manage to do the last one? the ln|3x-6| graph?
I could draw the right hand side, with asymptote at x=2, but I didn't know what to do to the other side!

I hope the grade boundaries are low, the past papers have been pretty easy until now, and all of a sudden they get hard, just in the crucial year!
13. Anyone do OCR?
14. I did really well i think.
I totally messed up the 7 mark integration q (couldn't remember how to use the formula), but the rest was easy!
15. such a ****ing gay paper. resit yes please
16. for me i find p2 relatively easy, its a resit for me and yeah ! crap with the tricky identity question.. i spent almost 1/2 hour doing it.. initially 10mins trying to do it, found out time's against me, then skipped it, completed it within the last 20mins, i went to expanding up the tan2a, 2tan²a and all , anyway this is the solution

prove

cot2x+cosec2x=cotx

LHS:

tan2x+1/sinx

cos2x/sin2x+1/sin2x

(cos2x+1)/sin2x

then u use identities to convert it

2cos²x/2sinxcosx

- cancel cosx on top with bottom -

2cosx/2sinx

cosx/sinx

1/tanx

cotx

the others were easier.. i just hope i didn't do any careless mistakes, touchwood
17. some faggart had the exam paper, see the previous p2 posts
