btw, for qn. 10(iii), it is asking for the least and greatest value of modulus of z, and least and greatest value of argument of z..

the greatest modulus is the farthest point on the circle ( connect the center of the circle and the origin. continue this line to the farthest intersection). Analogously,find the least. As for argument, draw the tangents(two) from the origin to the circle. The points of intersection will have the greatest and least value of arg(z).

Hmm.. the points of intersection between the circle and the tangents right?? how did you calculate the largest value of argument of Z??

For vectors, the first part, p = 9 and part (ii) I forgot my answer.. sorry about that.. hehe.. Oh yeah, partial fraction I got A = 6, B = -2, C = 1.. did anyone get the same values as mine?

I asked one of my friends about the paper and he said it was easy! Sigh.. but most of my friends find the paper quite tough.. how about you guys? I hope the GT will be around 51? Because nov 2011, paper 33, the GT was 51...
