    You're wrong, it's impossible to divide by 0, so the cot2x=0 is impossible and not a valid answer.
    hi arched.....how you doing?

    i hope i am wrong. and you are right.. my only answers were 22.5 and 112.5

    how did you find the paper by the way??

    For questions 9) i) b) i used log instead of ln (the c2 method) and solved it and everything, but i got x=log(...) instead of ln(...) and i didnt cancel out e , how many mark will i lose, even though i got the answer as an exact but not in the way they wanted it. THEY DIDNT SPECIFY THAT THEY WANTED IT IN LN :P , anyway its my bad. xD
    two of my classmates did that too

    Fg(x)>= 3

    its equal to aswell cos (x+1)^2 + 3

    draw that graph it touches three...simple quadratic (completing the square) from c1!!!




    remember ((ln) and (e)) canceled to become the equation above ^^
    it is (x-1)^2 + 3

    still anyone
    can someoen please say if question 8)
    45 and 135 cannot be solutions i put them back into the original equations!!!

    someone correct that mark scheme or prove me wrong please!




    dammit
    i lost that too
    6 marks gone

    oh wait -->



    i did that and put fg>= 3
    hope thats correct

    unles with the composite function you have to take into account that g(x) is x>1

    lost 6 marks (+ more if i had to include those two with the cotx=0) !!
    that!!

    i did what you did...so i am wrong as well

    Who else thinks that June 2006 was not even hard compared to our paper?

    I mean since June 2006 had such low boundaries, we should get lower! =(

    hey there, for question 8 are the solutions only 22.5 and 112.5, since cot2x cannot be equal to zero?

    so for the last question, is it fg(x)>=3, since the graph is (x-1)^2+3

    so you can include 3, i hope!
