normally around 150

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
