# P3 Anyone Do OCR?? watch

1. yup 77.7degrees

and minimum value of x = 1/e

for my integration i just used between e and 0, not sure if that right though.

It said bounded by x-axis (x=0) and line x = e

The vector question was so so easy though i have done p6 which makes p3 vectors very easy indeed.
2. If its bounded by the x-axis then y=0 not x. stupid idiotic question though!!!
3. oh yeah lol whoops!

what did you get for t as x get 'extremely large'

i got t = 2

i have to say their wording was not very good
4. I think I got something along the lines of t=aaaaaaaaaaaaaaaaaaaaaargh my head hurts

lol i dont remember exactly, it was soemthing along the lines of 2 i think. lol i really dont remember. i am now trying to block it all out of my head so that i dont get any nightmares tonight!!!
5. hehe my general solution was along the lines of...

x = 1/ [k(t-c)]

using the values, i got k as 0.5 and c as 2
6. the "gets very large" that was really unmathematical, if they'd defined it a bit better i think i might have known what they were talking about. maybe some of the marks were for interpretation....
7. yup, rather surprising from ocr, they're usually quite good.

you'd expect edexcel to be making those kind of loose wordings but not ocr!
