    This may sound a bit obvious but make sure you use all the information you've been given, eg in earlier parts of the question

    I'm not sure - personally, I'm planning to do an easy-ish paper this morning just to get myself in the swing of things, whilst not overburdening myself

    Haha I had the same panic yesterday 😁

    Btw guys which volumes do we need to know for core 4? Cylinder,cone...?


    Posted from TSR Mobile
    I hope they're all given but 4/3pi r^3 for sphere, 1/3 base area x height for cones/pyramids and base area x height for cylinders/prisms covers pretty much everything anyway and it's not too bad to learn

    you should never end up with a negative area, even with the limits that way round. it will always work out as positive -- and if it doesn't, you've gone wrong somewhere.

    Any tips on finding out a vector of something like AB?

    say, you got AB on L1, how do you find the vector for it? is is b-a or a-b? I always get confused and end up having minus the angle that I find by 180....

    Can someone explain b) to me. I don't quite fully understand why you take out a factor of 1000 . Why wouldn't you rearrange 7100 to = 8-9x and solve for x and sub that back in?

    THIS IS NOT TRUE! He has used the limits the other way round so he would get the negative of the correct answer so the area cannot be negative so its positive! He will still be correct

    if you did that, x would be bigger than 8/9
