^ yes lol. Wrong answer. Maybe get 1 or 2. btw, for part fii), I just said n is a multiple of 4. Did you have to strictly state >0 though ?

For geometry, last part. I just said how tangents from an external point X are equal (SX=CX), thus SX must be a tangent. And T is collinear with X, therefore ST is tangent. Still get that 1 mark yeh?

It can be either. As long as you get the right answer.

change it to 1/12 hours

^ confirmed cii) is right. thats what i got

I got 180(60-cos(a)) / root(901-30cos(a)) ... don't know how you got sin(a) on the top, because you differentiate with respect to 'u', not 'a'

fuckkkkkkkkkkkk. because sinx = sin(180-x)

5 is definitely D. Pair them up, to make 6! ways. Then x by 2! (=2) since C and L can be in any order. Also 11fii) multiples of 4. For 14biii), I actually found no angles that worked simultaneously for both. Question problem, or what? Test out your values of theta and see if they satisfy both...

83 raw mark. What would that scale to?

Re: General Thoughts: Mathematics Ext 2 the numerator is the derivative of the denominator... .5 log (e^2x + 1). then sub in limits

Re: General Thoughts: Mathematics Ext 2 This is the answer. What you guys talking about?

^ 15b) i) real coefficients - roots in conjugates II) just factorise ii) for there to be a real root, z-k=0 and kz-1=0 simultaneously. therefore, k = 1 or -1; sub this value in iv) product of roots; modulus^4 = 1. and they all have equal modulus. therefore = 1 v) use sum of roots vi) no idea...

Go to the last question and hope to God I don't see a whole lot of sigma signs hehe

There's 5 minutes reading time, but it's pretty much impossible to answer the multiple choice in your head. So what should we do?

Do you think you could use like leadership style and rewards as strategies to help implement and reinforce the need for change?

I was hoping that would be the case for someone. I just don't know what to talk about for the change management strategies; that's whats killing me. Chapman's business textbook kind of gives strategies, but they aren't in enough depth that you would need for a business report.

bump

what's the new site? it's still down. btw how the hell did you get access to all those papers EDIT: nvm, found the backup site

is the baulkham hills 2012 trial hard? I was just about to start it. It didn't look too hard at first glance

where do you get these pre-2000 hsc papers, with solutions? anywhere online?
