# C2 intergration, need answer Watch

1. (Original post by SophieL1996)
I thought it was obvious when I said find the area between AB and the curve, sorry I should have made it clearer.
That's ok. It is possible to find an area between a line and a curve without them intersecting.

No it is not clear, because AB and the curve do not necessarily have to intersect at A and B. You gave us a question where we did not know the equation of AB.

Anyhow.

Boom I have it for ya!
=2x^-2+x
=> S = (2x^-1)/-1 + (x^2)/2
when X=2 S=1
and when X=0.5 S= -31/8
1-(-)31/8= 39/8
Area of trapezium= 8.25
8.25-39/8= 27/8
Ill take a fiver for that
Fixed it

ok whatever

I know how to do it but I keep getting the wrong answer. Could someone please post what you get . y=2/x^2 +x. The points A and B have coordinates (0.5) and (2) , these are x-coordinates. Find the area between line AB and the curve. The answer is 27/8 and I got 10.25 ...
Pls can you upload a pic of the question? With the graph shown too, you can upload it directly on tsr or link it on tsr using a image hosting website. I know it's been answered but i would like a crack at the q since im re sitting c2
