    i think it is 11/64 cz..the area of the triangle was 0.5x(3/8)x(2-0.5)..=9/32
    integrated region= x(x-1)(x-2) from 1 to 0.5= 7/64
    9/32 -7/64 = 11/64

    What was the answer for the last integration question?
    i got .1 something

    Are you sure about this because i got 11/64
    yes I am very certain.. majority of my friends simply subtracted the equation of the line from that of the curve and then integrated from 1 to 2, however, there was still further calculations required ( if that's the method you used) so they missed out on 2-3 marks.. equation of the curve was y=x(x-1)(x-2).. so when y=0, then x can either be 0, 1 or 2.. easiest way of doing it was integrating from 1/2 ( which was given ) to 1( that would give a small portion of the area under the curve) then subtracting it from the area of the triangle

    Omg thank God I did that! Could you tell me how you solved the simultaneous logarithm question please?

    No worries it's fine. To be honest I think my main problem in this paper was the time. I tend to make a lot of careless mistakes and if I don't check them...That just sucks I guess. For the integration question I got a minus answer because I didn't do minus minus in the step before that. Would I lose method marks if I changed the sign at the end?

    I think you'll get full marks cause area is never negative, so long as 11/64 was your final answer I think you're good to go Are you sitting for M1?

    Wait no way please tell me you meant to write 27/64? Because I did the same method as you mentioned earlier when calculating the area. And no haha lol I do S1 because I hate Physics and hence M1.

    sorry I meant 26/64 hahah lol physics and M1 are so easy.. our teacher said you can only do M2 if you get 80% or above, im afraid I might be the only one doing M2 in my class

    Right may be you truly are an Einstein. No way I did Triple Science Physics GCSE last year and it had 2 extra AS modules which were so hard and annoying! I remember learning stuff about logic gates connected to transistors and diodes and all the rest of it! It completely put me off lol.

    He's my hero indeed! but physics can really be stubborn sometimes, lol yeah that's right but A-level physics is nowhere close to that haha

    There are some questions I remember but couldn't do
    Any ideas on the answers?

    - The question with the circle with centre (a, 3). Another coordinate on the circle is P(4, -3). Find a
    I think it was 25/8 ...can't remember tho.



    - The logarithm question to convert log 2 y = 5 - log 2 x (the 2's should be small) into y^2 = k / x
    BTW it was 2log2y=5-log2x and k was 32





    - How to solve the logarithm equation simultaneously with another equation I can't remember
    I used x power -3 =y and then substituted y in the equation to find x...I think x was 1/2 not sure tho




    - The answer in the Sum of n question Where a = 97 and d = -3. I think I got 56


    I think I got 66... It was n>65.6

    I found the paper to be of the same difficulty, if not just a little easier, than the ial jan paper, so i doubt the boundaries will increase by much
