    Is there a list of shapes on the syllabus that you could be asked to make out of vectors, cause I know 7 and 3 of them are squares. -#prayforsquares

    Differentiate it again. Make it equal to zero and rearrange.

    I'm so scared for this exam. I was feeling fairly confident (and very confident for core 3...) but after how that exam turned out I'm just dreading what sorts of questions could come up...

    None on the syllabus exactly because we should know it from GCSE. I would recommend looking at (areas + general facts)

    Rhombi
    Kite
    Parallelogram
    Trapeziums

    and the good ol' squares and triangles

    parallelogram has 2 pairs of parallel sides
    rhombus doesn't. Rhombus also has 2 pairs of angles which are equal to each other and opposite each other i think
    also parallelogram parallel sides are of equal length, and i think all the sides of a rhomubs are equal length

    If a shape ABCD has an angle that isn't 90 degrees and all the vectors (AB, BC, CD, DA) are the same length then it's a rhombus. 90 degrees its a square. All I know.

    A rhombus is a parallelogram. But a parallelogram is not necessarily a rhombus.

    Exactly. Also like how all squares are rectangles, but not all rectangles are squares.

    Could you explain the concept of a 10% quartile please? I am a parent, not a maths student, so I don't understand that.
    errr, there is no such thing. A quartile is a 25% chunk. 10% is 10%. nobody knows what he means.

    I guess the argument that a lot of people think they deserve a A or A* because they spend a few weeks memorising mark schemes from past papers is sort of a valid one - although he was just being a massive douche about it.

    With the mood AQA are in this year I doubt it. Wouldn't be surprised with an out of spec vector question.

    Can anyone tell me how to do June 2015 6c?

    Also, in vector equations when you have to square the vector, why do we usually have to do that in a typical question? Whats the purpose of that?

    Thank you
