AQA A2 Mathematics MPC3 Core 3 - Wednesday 15th June 2016 [Official Thread]

When inputting the limits did you get (ln1) in your answer somewhere since it was ln(3x) and one of the limits was 1/3 and which lead to the final answer
pi(-2(lnx)^2)

What were the limits for the substitution question?

For the second part, finding an estimate for just x^x ? Did no one else get this?

For the Vol of revolution I got 'in its exact form' Pi(4-2ln3 -(ln3)^2).
This seems correct as when I typed the integral into my calculator and took away the value I wrote down above away from it(expecting to get 0 if my answer is correct) I got something like 2.4x10^-13. So I think my calculator rounded off slightly, leaving a very small decimal left over, what did other people get for this question ?

For Q9), the show that secx - tanx = -0.2

Would I get a method mark for putting it in the form 1/cosx + sinx/cosx = ?

I got 90% UMS last year across all 3 modules, on this paper I probably got around 45/75

Yes I got 1.51. I checked with my calculator and it was indeed 1.51



This is correct



No, it wouldn't have got you anywhere

200/200 in C1/C2 so far, and 40/75 in core 3.

I know exactly how you feel, my confidence is crushed, I have an exam tommorow and cant revise (will start soon) because I am so angry.

I needed an A* for my firm, I still have 6 exams knowing I won't be going to my firm university.

Oh if that were true...

Let's hope you scrape a B and get 100 in C4. Stay positive!

That wont work. You'd need 80% on this and 100% on C4 to average 90% in order to get an A*. And if he's already got 200/200 in c1 and 2 he's pretty much guaranteed an A (as you only need 480 overall).

well **** lol, the paper wasnt that bad, it just required a deeper understanding of topics, if you were only doing aqa papers for revision your doing somethign wrong, they dont prepare you for ****, do edexcel, soloman, ocr maybe. doesnt matter how many questions it depends how fast and good you are (comes wiht practise) the boundaries will roughly be the same as last year if not maybe 2 marks lower maximum

Lapse from me, there. Do you think 52-55 could scrape an A for me, so I could really go for it in C4? I got 278 ums last year, so need 67 ums on each for an A

Ok, but the Volume one, I am certain that it was 2 not 4 in the brackets as the intergral was -ln(3x)^2/x - 1/x, so it was -1--3, which equals 2

did anyone do the finding range question of 5 marks??? #hateAQA 😡

Hi
Can somene explain to me how to work out the question which asked for the range of the function. I had no idea how to do it cos usually theyre like 1 or 2 marks. Thanks
