    what will the grade boundaries be..... I lost about 7-10 marks ;(
    I think that I am in the same boat...

    The thing that I am thinking is that people who go on these forums, are steriotypically the kinda people who do very well/top couple of %, so they may all be saying they found it easy (though quite a few are saying it was hard), but that means that the majority of ppls found it harder than them.

    Therefore low grade bounderies (I hope)

    I was so stupid that I forgot that f(-x) meant reflection in the y-axis. How dumb was that!
    I think I did that as well :facepalm:

    I think the four solutions may be correct, since at tan 90 you have 1/0

    so cot 90 = 1/(1/0) = 1*(0/1)=0

    But how many marks do you think this is worth?

    I'm guessing that I got in the range of 62-66, which considering I walked out the exam about to cry (not really :P, but I was pretty upset), is pretty good I think. Should get me into the mid 80s in UMS I would have thought.

    Well, I think i did very well, the only thing I wasn't sure of was cot (2x) = 0 because if you rewrite it as tan 2x, it would be equal to infinity, and tan is equal to infinity at 90. Also if you re-write cot 2x = 0 as cos2x/sin2x = 0
    then cos 2x = 0 and you can solve that.

    BUT on the other hand, even if you do get values for cot 2x = 0 and then substitute them into your calculator, you will STILL get infinity/Math Error

    but the correct answer has four solutions!!
    I got those exact 4 solutions yesterday, but I'm staring at the question now, and I can't figure out what I was thinking! In hindsight, I'm pretty sure that two of the solutions are wrong.

    Ah. I think that's what I may have done.

    Personally, I think it will be about 57ish for an A.

    how hard is Core 4? Is it really hard? my teachers have said that if an average student in maths get 60 in C1.. s/he'll get 30 in C4.. but it was a generalised comment though, so yeah.

    Are you sure 45 is a solution, because i know if you express cot as cos/sin it's possible, but i think that'd be harsh because if you put 45 into the original equation you will get math error. After all you are finding solutions for that equation.

    I am pretty sure there are 4 solutions as 1/infinity = 0
