# P1: How Was It For You? watch

Announcements
1. (Original post by BlueAngel)
The question on geometric series.

To get the common ratio, did you divide the 2 consecutive numbers???
I think it was 9/10 or 10/9 or summit.
What did everyone do here?
9/10 = 0.9 r = 0.9
2. I think the series question was:

A) PROOF! - yes! I revised that this morning.

B) Sum = 100

c) Difference = 9/10 or 0.9

d) 10/11
(because 10 = X/(1-X)

therefore,

10(1-X) = X

10 - 10X = X

10 = 11X

X = 10/11

correct - well done

also, on the graph of C and l, wot points did every1 get for where they crossed?

i got (1, -3) and the other one was somwething like (-4, 12) , but i cant remember the last one properly
i got those too...ne1 else get them?

i couldnt do A), i hate myself...

for the first one 17 + 12 route 2

The second one 0.5 plus something like (8/3) route 2
did no1 get a - here??? sumthing lke 17-12rout2....wot was da q again??
7. (Original post by TheWolf)
mm i cant remember but i know that for one of them, there are 2 answers, for the other there are 4 answers
4 answers...i think there were only two answers for each of da trig qs

I said that that in the part you quoted!!!!

lol

Oh and the proof - you either knew it or you didnt i guess.
9. oh and i think there were only 2 answers for the triq questions as well.

Don't forget 0<x<360

not -360<x<360
10. (Original post by lgs98jonee)
4 answers...i think there were only two answers for each of da trig qs
im pretty sure that the 2nd one has 4 answers - the tan one?

no u said 17+12 route2 i think it is 17-12route2
12. i got a feeling I'm going to be borderline on this paper or 2-3 marks of the A because i see myself getting 64-66/ 75
i guess that means I'll have to work extra hard for S1... M1 went brilliantly

for the first tan one...there were only two answers right??? and for the second one there were only two as well???
14. (Original post by lgs98jonee)
no u said 17+12 route2 i think it is 17-12route2
oh right, yeah probably, minor detail

I messed up mechanics lol. and I will get about 50% in stats. I reckon stats is gonna be hard, esp. after these papers
15. (Original post by Ollie)
How did P1 go?

Which questions did you find hard/easy?

Are you going to repeat it next year?
it was a nice paper except from the last question..i kinda got confused! sayin this, what did every1 get for x-coordinate of Q??i got 11/3 and 4 for gradient that showed P and Q were parallel..!??!!any1 agree??
16. erm, i didnt thing P & Q were paralell!?! I thought you had to prove line PQ was paralell to the X axies?
17. Q's coordinate was def 3 i am afraid

u got 3x^2-14x+15 after differentiating
and so this was (3x-5)(x-3)=0

so x=5/3 (other turning point which u could show using 2nd derivative) or 3

pls correct me if i am wrong

so did every1 get two answers for each of the trig qs????????
19. (Original post by lgs98jonee)

can you remember the calulator value for the second one?
20. i think Q was somethin like (3, 12) and P(which was given) was (1,12). for the proof of it being parallel, i wrote that they y values are the same therefore it must be parallel to the x axis, but friends were saying that you had 2 state the gradient of it was 0, but i didnt write this down was i tht it was 2 obvious!! do you guys think i will be deducted for this?
