top 5 at my school told me 9 was A - I guessed it cos of time, so idk.
exactly the sameYeah I think aDimitris are correct except 9 should be A (I put B though lol)

pree sure 10 is DI got 10 as A
break it up then use u=-x to get A instantly
Yea I know but I was in a rush so I chose A :'(if you break it up as f(-x) you get + f(-x) not - f(-x)! i nearly fell for that
Isnt 7) BHere's what I got:
1. D
2. A
3. B
4. C
5. C
6. B (answer was D -.-)
7. A
8. B
9. B
10. D
Definitely got a few wrong, was worried about time
Fcking hell. WTF, I though B said f(x)+ F(a-x).pree sure 10 is D
How'd u get A? It just can be A because if f(x) is even then A=0 and if f(x) is odd, then the original question is zero.I got 10 as A

the only issue i'm having is that i did d/dx v^2/2 in order to check it, and it didn't work :SFor 9, differentiating (A) I got dv/dx = 2cos(x-1), a = v.dv/dx = 2v.cos(x-1), sub x=1, v=2, a = 2(2).cos(0)=4
misread the minus signHow'd u get A? It just can be A because if f(x) is even then A=0 and if f(x) is odd, then the original question is zero.
