    can someone please put up the worked solution to question 5(i). starting to panic
    Agreed but no one will upload it this evening I don't think. KPrime will be uploading it tomorrow though. I suggest just avoiding this discussion until KPrime uploads his solutions.

    Hey, how many marks would I lose for part 9c for having -5 instead of 5, providing that i got ln(2+2e^-1) - the ln right, but not the 5.

    A. R= sqrt(5)
    a= 26.57°
    B. 33.0°, 273.9°

    Finding the normal when x=3 in the curve you found in part (a)

    It didn't specify having to leave it in a certain form like it usually does so I guess it doesn't matter which form you leave it in just as long as you have the correct values.
    REALLY? FVCK YEAHHH, cheers.

    Does anyone know if there's a list of how many marks each question and part was worth?

    Thanks

    Looking at the MS from June 2007 q8 (very similar to this one!) I think you'd drop 1 mark.

    You didn't need to simplify 1/2ln(25/4). The question didn't say leave in its simplest form, it only said the exact coordinate.
    Are you sure? How do you know?

    I'm fairly sure it listed them: i, ii in exact, iii
    And then 'give answers in simplest form' at the bottom. I'd be surprised if they gave a nice root solution and didn't ask for simplest form
