    May/June 2012 paper 41. I am having trouble with question 9 (b). g(x)=7 -2x (we multiply by -2 and add 7) so inverse we will divide by 2 and subtract 7 so it will be x-7/2 but the mark scheme says 7-x/2 . I don't understand why.

    Thank you very much. Actually I got the formula from the mark scheme. I thought we were suppose to memorize it. I didn't recognize this as a sequence question. What about part d. I tried n+1=n/2(n-3)+30, but I can't get an answer

    I am also having a problem with this question. I solved part (a) and (b) and c(ii), (iii) using the formula: number of diagonals=(number of sides/2)* (number of sides-3) but I was not able to solve c(i) and d.

    Please help me with this question " May/June 2010 Paper 22 Q8" . I am having trouble with the sin cosine graph. I tried using the formula sinx=sin(180-x) and cosx=-(cos180-x), but it doesn't work.
