    3) Skew
    4) (pi/2 ,1), (pi/6 , 3/2)
    5ii) 1/2 ln (root 13)
    cant remember the question: (0,3)

    Some of the answers i remember...
    I got 0,3 for something as well!

    But for number 4 my y values were the same as each other (though I can't remember what it was)... another question down the drain.

    OMG! I've done 1/2lnsecx instead of lnsec2x. Now I'm depressed

    Yeah see this is what I thought, but I plotted the graph on an online plotter and there's only two. Why is this?
    No there should be 3. I plotted it on a graphical calculator and there were 3.

    Intergrate tanx and you get ln(secx) I just guessed tan2x would be ln(sec2x) then normal stuff from there

    Omdz how can my mind forget how to do intergration by parts .. made u=x^8 and it went AWOL lol (I know u=ln3x, but couldn't think) and forgot to half the base of the pyramid ting lol... Question 10 was a brain teaser but I got it after a while (x=0.1).. but how did people do part i) of 10.. That bamboozled me still
