Hi all, I just started the Ext.2 course yesterday and need help with this question: <img src="http://latex.codecogs.com/gif.latex?z\in&space;\mathbb{C}$&space;such&space;that$&space;\frac{z}{z-1}&space;$&space;is&space;real.&space;Show&space;that&space;z&space;is&space;imaginary.$"...

Hello all~ My HSC courses are MXI, MXII, English Advanced, Chemistry, Physics, SOR I. Aiming just to do my best ^3^ Happy to help people, as long as its within my capabilities.

Wow =='' So short!! But effective eh? I probably took the long way since I used parametrics and chord equations. Haha good job on your side.

Ooh yeah sure: Hopefully you can read, handwriting and scanner aren't the best...

I do have the solution written up if you want it? But if you want a guide best to ask Mr HSC2014 haha....

I'm in! As long as I know what I'm doing that is.

Mmhm Yearlies (Not that I usually talk though haha.... So sad T-T)

OMG I figured it out =='' Haha Thanks for the advise, good inspiration.

hmmm... either the basic 1/2bh or trig but there's no angle. So the most appropriate is the basic one... hmmm. Base is probably PQ but perpendicular height not sure...

This question is just throwing me off. Part ii asks to find the area of the triangle.... No idea on how to go about it. Help is much appreciated!

Ohhh okay now I get it; thanks!

Uhh I never actually learnt in class how to find the amplitude and how to find the max/min in the function.... This just happened to appear in one of the past papers. HELP!!

So it would be max = 1 and min = -1?

Hi all, just a bit stuck on this question, help would be great! Part b (ii) that is.

Hmm...Those who don't freak is due to that "Year 11 doesn't count towards HSC" mindset. On the other hand, there are people who do freak out due to first taste of HSC in the yearlies (where everything you've learnt is in the exams)

Dunno if I'm right but it should be this, excuse my crappy handwriting =='

Hi all, just wondering if I could get some help. Our class is having an essay with an unseen question on Judaism. The content is as followed: - Origins - Principal Beliefs - Sacred Texts and Writings - Core Ethical Teachings So what I'm asking about is what type of question am I expected...

Basic Arithmetic Algebra and Surds Geometry Circle Geometry Real Functions and Graphs Trigonometry Permutations and Combinations Straight Line Graphs (Coordinate Geo) Quadratic Function Polynomials And just started Calculus This is an alright speed isn't it?

OMG =='' I see what I did wrong now. Thanks a bunch.

Yes m= -9 sorry forgot to say answer. And I did what you said before... but I think I'm doing something wrong.
