Would greatly appreciate an atar estimate because calculators just don't trust them personally: Advanced English 85% (10/120) Mathematics Ext 1 95% (2/18) Mathematics Ext 2 85% (2/13) Physics 85% (5/28) SOR II 95% (3/55) And of course provisional band 6 mathematics advanced Thanks...

That would be wherein the problem lies... I dont quite understand why though?

I don't have an issue with any of it, but this one question is totally messing with my head, i get different answers by equating coefficients and by letting x=-1. Just totally messing with me :( (4x2-2x)/(x+1)(x2+1)

Diarys are meh Unnecessary IMO

Yeah i did about 10 hours today, reading over notes, selection of questions from Terry Lee, and 2 topic tests (not overly difficult albeit) but i feel much better about it all now, back in the zone haha

I have been redoing my work for complex numbers from last term to consolidate the information, and i am finding that my understanding is not as good as i thought, i did pretty well in the test we had (85%) and was second in my class, and im just wondering if anyone else is having these...

Yeah we did :) Not too bad tbh, need 85% plus to drop my 11th unit so quite nervous haha

answer is a semicircle in quadrant 2, starting at i, ending at -1?

How do i get the other result? EDIT: I think its multiplication by -i am i correct???

I thought so, thanks guys :) As a side note, the locus arg((z-i)/(z+1))=pi/2 Will be a semicirle between i and -1, where a line between the two is the diameter of the locus, which is a circle?

no i dont have answers, its from the pittwater house paper on here

Yeah man, proper green tea is the shizzzzzz it tastes like freshly mown grass ah blissen

Having a bit of difficulty with a question and unsure whether my approach is correct? "z1=4-i, z2=2i and z3 form vertices of an isosceles right angled triangle, with z3 the right angle, Find z3." Is the question, my working went along the lines of: Vector z3,z1 = (i) x vector z3,z2...

Doing ext 2 myself at the moment and studying complex i personally think the harder stuff is the trigonometric applications as well as some of the geometrical representation questions which are really abstract

Hey guys, my class has our first official Ext 2 task coming up next week, on COmplex Numbers and Polynomials, i dont have too much difiicltuy with past HSC papers, so is it safe to assume the task will be of that level or easier? Or as it is focused on two areas can they make it more difficult...
