AQA Mathematics Module 5 Paper 2H (Calc) Unofficial Answers (10/06/2011)

Wouldn't that still be length because it would be l x pi + some other l x pi, which is just two lengths added together.

I think RedUnited is correct. In the calmness outside the exam room, I think it should have been length. Unfortunately, I put area as well - oops!

Can anyone remember how many marks the question was worth?

Yey, I think it was only a mark. I was so close to putting area but then I remembered on mathswatch this exact question came up and they said it was a length.

It was 3 marks - 1 per tick.

What did everybody get for the rearranging of the trapezium equation?

i got something like 2A/h + a = b

And the one asking to find the value of cos x between 180-360 when y=-0.5 is cos 240

Glad i only got the drawing of the sin graph wrong and forgot to divide my 5 by 2 for the first question so i'm down to at least 66 now :frown:

answer for the question asking to make b the subject of A=1/2(a+b)h is b= (A/h)/0.5 and the answer - a

You're right, sorry that's my mistake.

First post duly changed.

-a, not +a.

You probably wrote that though and remembered it wrong. If you checked your answer (with the numbers from part a) it would have been obvious.

2A/h - a = b was the answer I think ,sorry my mistake earlier

I don't remember, but:

(1/3)x - 4 = 1/2
== x/3 = 9/2
== x = 27/2
== x = 13.5

And now, I do remember writing that! By the way, as I've written, it was -4 and not +4 as you stated.

If anyone is a beast at remembering question numbers, I can get the first post looking more organised.

Lots of questions with answers there now, if you can remember more questions - keep them coming!

Im sure it was +4 as I checked my answers rigorously, I got the answer to be -10.5=x
Also, on the rearranging question (2A-ha)/h is also correct

Find paper 1H (non-calc) unofficial mark scheme here.

b)
Q: Find a value of x where cos(x) = -0.5
A: 120

^part b may have been the reverse, I don't remember! Answer was either -0.5 or 120, where the other was given.

(See method here.)

Part b is wrong because the question was between 180. and 360. find the values equal to ...

It was 240 I think.

I thought the paper went alright but I screwed up the last question worth 6 marks :frown:

I might get 1 or 2 working marks, hopefully I'll still get my A*

Perhaps.

If others think it was +4 too, I'll change it.

Correct, but not complete. You've left h on the top and bottom.

If you then do (-ha)/h you get -a, hence my:

-a + (2A)/h on the first post.

You may well get the mark, but for the sake of an (albeit unofficial) mark scheme, I'll leave it in its most complete form.
