    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.

    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

    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....

    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!
