ALHAMDUILLAH IT WAS GOOD!!!!!!!I HOPE I WILL LIFT MY P1!!!!!HI EMMO

 

[kim anika]

wat ans did u get for f "(x) question?

wat ans did u get for f "(x) question?

Lemme see what I remember after all this time
First question x=0.5, Y=4
the venn diagrams was false false true
For f''(x), x=9
For Q12 OR, p=-40 q=-8 (or vice versa can't remember), g(x)>8 (I think), the values of x for gh(x)=12 were e^2 or e^6
The vector question, first one was 9i+45j, the second one was 13 units, the last one was 4/3i-2j (checked if CD was parallel to OB and it was )
For the height of the cuboid it was 4-sqrt3 (i.e. a=4 b=-1) for the graph a=3 b=8 c=7
That's all I remember atm

mmm what about the integration of xlnx? i got something really weird and long... [something like (2x^2lnx + x^2)/4]
and on the venn diagrams i got false false false but i think i didnt see a ' on the last one
area of the sector with triangle was soemwhere around 180
area of trapezium was 55
fukin vectors got last part wrong
and q12 either, x>k, smalles value of k = 5, and completing the square:
a=2
b=-5
c=-13
i think that's all i remember at the moment... keep adding answers ppl!
