Simpsons rule can be used to find area, just like true integrals can, but it also evaluates things. It was a log curve, so the area under x axis exceeded the area on top, making it negative. As it was evaluate question, thats all you had to do.

As for the marks - hopeful 6/12, realistic 4/12

>The correct answer ws 56.33333333333333333(I did not get that). Instead i got 32 root 3 which was wrong.
>What pissed me off more was wen I came home I quickly did the question and got the right answa, but in examination conditions I fudged it. I h8 that feeling.
>9/12
