Hi, I met with some difficulties for the 2oo7 tys E maths paper. firstly, their vector question shows 3 tirangles on a grid and the question given is : the translation T, maps triangle A onto triangle B. Write down the column vector representng T. Then there are those anticlockise rotation of maps, etc.
I don't seem to encounter such questions ever in my 2 years of upper sec education. is the syllabus out? and the construction question is also strange to e. they give a you drawing of a quadrilateral and ask you to construct a locus. I never know what a locus is. Is that required in the syllabus of e maths for 2009?
*edited: anyone know if there are angle angle properties relating to trpazium? eg. sum of opposite angles = 180? can you list down the properties of trapezium for me. thanks!

i only learnt vectors for A-levels!!
and i did Math C and Further Math!!

Dun worry. All these no need know already.
I believe trapezium is still counted as an n-sided polygon.
Therefore total sum of interior angles is
(n-2) x 180* = 360*
thanks for the useful info everyone!
so opposite angle of trapezium is not equal to 180 deg? by the way, for vector questions, if our answer is 1/4 (a+b) , do we have to expand out to 1/4a + 1/4b or leave it in simplified form?

Hi anpanman,
I believe that it will be more appropriate to expand it out rather than to "factorise" it, since it is a vector. I don't think there will be any penalising for not expanding it out though at E. Maths lvl.
Cheers.

I looked at TYS answers too, some are factorized, some are not. Thanks for trying to help !
Anyone has any idea about this factorizing thing too?
