# FP2 Mock Paper B: minor error in markscheme?Watch

#1
Hi,

I've just completed Edexcel's Mock paper B for FP2 (new spec), and have come across what looks to me like an error in the markscheme n question 7(c)

I've attatched the question and the markscheme for the question. Basically, the method, as far as I can see, is, since we have an expression for v and know that y = vx, simply multiply v by x to get the expression for y. In the markscheme, they've done this for the complementary function (A cos 3x + B sin 3x), but NOT the particular integral (1/9x^2 - 2/81.) Since this is just a mock paper, and Edexcel tend to be a lot less careful about error checking these, I'm presuming this is just an omission, but wanted to check I was not missing some knowledge...

Thanks!

And they managed to turn a cos into a sin in that last line as well,....

Yeah, it's an omission on their part.

could you post the whole mark scheme for this paper? Can't find it anywhere online.
Or if not it all, just question 8?
Thanks

I got the markscheme from this thread; scroll down and you should find the mark scheme for past paper B.
