It all started off so well but then it tailed off sadly. Although, Luckily I added 64 to 162 so hopefully that is correct for integration.

can someone show me how they did question 8 part b with the k in it.
i did this .

4sin^2x + cos x = 4-k
cos x = 4 -k - 4sin^2x
cos x = 4 -k -4(1-cos^2x)
cos x = -k +4cos^2 x

then i subbed 3 in as k , made a quadratic and solved

Q2 is wrong...its not 20, its 25!!

R was 20 as the change in y was-4 and the change in x was 2, 2^2+4^2 was 20

No,the area is always positive, you got negative because the area is under the x axis, but you have to change back to positive, so it has to be 194+32=226

oh how many marks would I lose cause I got all the steps right apart from the adding ?
