i thoguht the paper was pretty good all the way through except question 10.
There for part 2 I prooved that the equsion wasn't equal to what they gave me. loose one mark i hope.
part 4 I did a few steps but didn't get x equal to something, father some weird fuction of x is equal to something, I'm hoping for one mark.
Part 5 i didn't really get. i got as far as recongnising it had to be a derivative, took the derivative then failed to solve the complicated question again i'll be pleased with one mark, but other than that the rest of the paper was a sinch.
There was also one Question 3 part 4 where I came out with some weird nomber for an area that I suspect I got wrong. If anyone could remeber what they got there could you tell me whether it was a round number.
Any thoughts on question 10 would be great too.
thanks
i think, this is from memory, but dont quote me on it, it was 6.5 units bad memory but, had square root 5's in it that cancelled out.
but seriously that paper was god's gift!!! if i didnt make stupid mistakes (highly unlikely) i think i could get full marks in q1-8, only thing i couldnt get out in Q9 was proving what the volume was equal too, but pretty sure i would of got 1/2 for it, and then in q10 haha max 5/10 at least 4/10, so hopefully should be pretty dandy, but q10.b) has always been pretty gnarly for the last 5 years, i.e. last years freakin probability!
just dont even want to think about extension....will be the death of me ahaha.
