    top left area(curved triangle thing) = area of square - area of quarter circle
    shaded = square - 2* top left area

    Slightly weird question, but I was only curious: is anyone taking in anything other than basic stationary (pens/pencils/rubbers/rulers/sharpeners) into the exam?

    I obviously don't mean any of the 'banned items', but things like compasses, protractors, etc. I haven't ever actually used them in past papers, but they could *perhaps* somehow come in handy, I guess... (sorry, my pre-exam paranoia has started to kick in )

    i was literally going to just go in with 3 or 4 pens no pencils rubbers or even a ruler, ive never used a ruler in MAT and somehow i got an A* in A-Level :/

    If we can prove that maths=magic. The definition of magic is 'the power of apparently influencing events by using mysterious or supernatural forces.' Ok, I think we're defo magicians!

    in Q1 is it just 4 marks for the right answer so working out doesnt matter or are there method marks too?

    also im stuck on this and dont understand the mark scheme any help would be appreciated, im sure i know how to do it just had a mental block.

    In the region 0 < x 2π, the equation

    x
    0 sin(sin t) dt = 0 (integral)

    has

    (a) no solution; (b) one solution; (c) two solutions; (d) three solutions

    Hehe - I could never do that! I'm one of those weirdos who take in several rulers/rubbers into exams 'just in case they break/*something* happens to them' (no - it has never actually happened to me or anyone I know, but you never know ) Not even a pencil though?! :confused:

    ye im really strange in exams, if i see something ill get the answer but if im stuck i find it hard to stop doing the same mistake so i just repeat mistakes which leads to lots of scribbling

    I'm a little bit like that too actually Which is why I've been doing all of my MAT papers in pencil, but apparently they'd rather we do it in pen... I did my first one using a pen today, and it was a horrific mess How are you feeling about tomorrow?

    I'm not sure how to do it. I'm assuming it's an isosceles right angled triangle. Then I'm stumped

    nervous, but tbh i dont mind if i dont pass so im much better knowing that theres no pressure, because im applying to imperial and not oxford, and imperial isnt my first choice, getting very very weird results in past papers, ranges from 50-75ish so i have no clue on how its going to go tomorrow but ive been doing the past papers quite casually, none where ive properly timed myself, but ive noticed i do it in maximum 2 hours. how about you? confident??

    call the radius 1
    draw a line from the centre of the circle to the bottom left corner
    find the length of this line
    find the length of the line that cuts the large triangle into 2
    should be enough to give you the area of circle and triangle

    For e)

    Note that this is essentially the area of a square take away 2x the difference between a square and circle (if this makes sense.

    So find the area of the segment, double this and take away from the area of the square.

    f) This requires a bit of pythag

    Calculate the perpendicular bisector which grows through the centre of the circle and the origin. You can do this by noting that the radius' are each one so the hypotenuse is root 2. Add this to the other radious.

    Now you have the perpendicular bisector note that you are then dealing 2 isoceles (right angled) triangles. From here it should be relatively basic to find the area of the total triangle using 1/2bh.
