    will it be around 59/60 for an A in this paper Mr M?
    If its down to 56 I might jsut scrape an A but I guess It cant be that low...Looked at results from other papers. Highest was 60 n lowest was 56. Was a easy paper even though I managed to **** up big time...Probs be 58

    United forever AS for that question i posted do you think its 3/5 marks to get to that point without solving the quadratic. Seems logical as 1 mark each to find Sn of each summation and then 1 for putting them together to get a quadratic, right ?

    more to the point, how do you remember all the questions and marks, do you smuggle out an exam paper or something?

    haha i thought as much lol how would you have done it if you were integrating one equation though? rather than the two separately?
    See the integral I posted earlier. Just gather up the like terms (the constants) first.

    Was I not meant to get a remainder when doing long division because I swear to god the first part was X-3 is a factor and the long division was x+3....I got a +10 Remainder

    And I did equalty what Viqas I think did
    Would I get any marks
    And I put x = -2/3 or 2 for the top questions
    Would I loose a mark

    And for the trapezium rule part two....square rooting the answer is wrong I guess?
    Yes x +3 was a factor.

    Probably lose one mark for x = -2/3 or 2.

    Square rooting is wrong. By the laws of logarithms, you divide the previous answer by 2.

    I teach mathematics so no smuggling required.

    Mr M Please ANSWER THIS QUESTION !!!

    N(16 +(2N-1)x3) - 1/2N(16+(N-1)x3)=1256

    N(16 + 6N-3) - 1/2N(16 +3N-3) =1256 then multiply by 2 to make life easier

    2N(13+6N) - N(13+3N)=2512

    12N^2 +26N - 3N^2 +13N =2512

    9N^2 + 13N = 2512

    How many marks would i get for getting this far and then messing up the quadratic?
    Thanks

    There is no such rule but exams officers often don't understand the rules properly so they err on the side of caution.
