    The minimum of the LHS would be 4 and the maximum of the RHS would be 4 as well?
    Exactly, so the only time the two sides will be equal (all other times, the LHS will be too big and the RHS will be too small, so never equal - hence no solutions) is when both are equal to 4.

    Now does an x exist such that both \sin x = 0 and \cos x = -1? If so, how many? If not, well then there are 0 solutions.

    Ah right, they both exist at 180 degrees or Pi so it would be one solution.
    Thank you very much

    Hi, I am going to be applying for Maths at Oxford but I was going to be applying to Cambridge. I therefore have not looked at the MAT yet and would appreciate any help at all. Please message me, I have skype and would love to group sessions. How much practise do I need to be doing between now and November?

    It definitely depends on how much you know right now. There's around 2 months until the exam so there's definitely some time to prepare. Message me your skype so we can figure something out!

    I just looked at Imperial for the MAT and it turns out you don't need to sit it for Computer Science. Is there any reason for this? They use it for everything else except for comp sci

    What trig facts do we need to learn.

    E.g sin30= 1/2
    sin60=(root3)/2

    hmm you probably need  \displaystyle \cos^2x + \sin^2x= 1,the three  \displaystyle \cos2x ones,  \displaystyle \sin2x = 2 \sin x \cos x .

    Id say learn the values of sinx, cosx and tanx for x = 0, 30, 45, 60 ,90 ( degrees).

    also  \displaystyle \tan x = \frac{\sin x}{\cos x}

    also as you probably know you dont get a formula book, so make sure you know the sine rule and the cosine rule

    theres probably more but thats all I can think of rn

    In terms of the syllabus, you'll need to be comfortable with using radians, tanx = sinx/cosx, sin^2(x) + cos^2(x) =1, and that sin (pi/2 - x) = cosx. You'll also need to know the exact values of sin, cos and tan for 0,30,45,60 and 90 degrees (it's not that bad to learn then by rote - remember one line for sin, then "reverse" it for cos, and applying tanx = sinx/cosx for tanx.

    Also, something that comes up a *lot* - remember how to work with the maximum and minimum of sine and cosine functions. And squaring something makes it positive!

    Also, note that if you've got something like sin(sqrt(x)), sqrt(x) increases slower than x, so the waves will get further and further apart. Similarly, in sin(x^2), the waves will get closer and closer together. You'll probably see a few examples in multiple choice questions.

    What's everyone scoring on the 2008 paper? I just got 67 but it's 2 years before the score data, as it's still a relatively recent paper I hope 65-75 is still a very competitive score?

    super roughly from 2010-2015 the average was 50, average shortlisted was 60 and average successful was 70 (obviously lower on the harder years) so i cant imagine 2007-2009 being much different.

    Id say 67 at this stage is super good, getting 70 will put you in a very good spot probably

    Thanks, even though i'm not applying to oxford (Cambridge lyfe ) I'm gunna apply to imperial or Durham so I can do the exam just to see where I am at the moment. Although if I do really well in the MAT and get rejected I'll be well gutted.

    Best of luck to you

    I got 81 in that paper (doing the comp sci questions not that normal maths ones, don't know how they compare) and found it quite easy compared to the 2010. I would still imagine the scores for those papers to be roughly the same as 2010-2015 though.

      It terms of difficulty, I think it would be about the same, but I can't say for sure because that's obviously subjective.
