Yo for 13(c) (iii) can we just state similarly? If so then i got that mark i thought i lost a mark there :/

Concensus is that you can, since it's a 1marker (I wrote by symmetry just in case).

Carrot, 11c) says factorise, not solve.

This is awesome! Thank you!

Although you missed part (ii) from the recurring integral question I think !

Thanks!

Which question?

The radius of circle Q14(d)(iv).

Thanks so much.

Damn. I made so many silly mistakes.

 

[Carrotsticks]

Finally, fixed everything. Thanks Trebla! Had the answer but was freaking out because I didn't rationalise the denominator so I thought I had it wrong, and I was at the end of my tether.

Could also be the 2x large red bull cans making me more jittery than usual.

Great job! =D

In 14 c ii - shouldn't the first term be rather than simply ?

Hey, I was just wondering for question 11 (a) part iii, do you think the HSC marker will accept 16777216 as well as 2^24?

I'm currently sitting on ~69. Depending on if i get marks for my last question or not.

 

[anomalousdecay]

For 12)c) I got 4e((e^2)-3) . Anyone else get this or did I just lose a mark?

All carrot's answers are correct.

Carrot, another one:

question 14div) (the radius one) there's a wee error.
http://latex.codecogs.com/gif.latex...r^2 \\20r^2 = 189 \\r = \sqrt{\frac{189}{20}}
must be the Red Bull

With that 10 marker and the induction and circle geo, I would say 100 would be super hard to get.
