Title: SCANNED COPY OF Mathematical Methods 2009 - Exam 1 and 2
Post by: MiCCAS on November 06, 2009, 12:40:07 pm
G'day,

For the interest of those who did not do the exam today, but wish to see it, I have uploaded it for your viewing.

Exam 1: http://www.michaelcasha.com/files/exams/Methods2009_Exam1_compressed.pdf
Exam 2: http://www.michaelcasha.com/files/exams/Methods2009_Exam2_compressed.pdf

If there is anything wrong with this scan, if I have missed a page or you cannot read some information, let me know and I will be happy to fix it and reupload.

for the last question i said that the approx formula was an existing val (2) + the area (rectangle) under the differential curve that is (f'(8) x h). where h is the width, i then drew a differential graph (no tangents) with the area shown and stated that because the approx area is bigger, the approx value was bigger then original

it's not what the answers say, but do you think i'll get the mark? or is what i wrote even true?

No I don't think you would get the mark, as you have not talked about tangents and the gradient of the function.
Approximation uses these not area at all.

I wrote; Tangent lies above the curve due to diminishing rate of change of , hence approximated value is greater than the exact value.

That was accompanied by a diagram as well as another couple of sentences explaining how approximation formula relies on tangents.

Thanks for the upload, I laughed at the Tas Jones question this year, I assume he died but the took the question out because it was too sensitive :x

That'd be about right - lol!

The differences between the CAS and non-CAS version are interesting. I see in the non-CAS questions they guide you through some bits. Personally I think the CAS was harder, especially the MC

I think CAS is meant to be harder?

As someone who does non-CAS Methods, I personally thought the paper was relatively the same difficulty as the CAS paper (I had a look through TT's solutions).

As for "guiding", we get "guided" because our graphics calculators can't do the same as your CAS - for example, we have to solve equations using algebra, and for probability (esp for binomial we have to do more groundwork before we can use our calculator - hence the "guiding") :)
