Hi there 2016'ers, including myself!

Welcome to the 2016 HSC 2U Marathon,

Some simple housekeeping rules:

1. Only post questions within the level and scope of 2U HSC Mathematics

2. Provide neat working out when possible

3. Don't flood the thread with multiple unanswered questions

4. Since HSC 2U Mathematics can be tested up to 30% of the maths you did in Preliminary, feel free to post the often odd and challenging questions

5. And remember to have fun and enjoy the beauty of mathematics (I don't really know if this is a rule lol)

Q1/

Re: HSC 2016 2U Marathon

Alternate question because if I think about it now it's a bit too early for integration.



Hint: Right-angled trigonometry implies you will need to construct at least one altitude on any arbitrary triangle.

EDIT: Extra - Prove the sine rule whilst you're here. (EASIER)

You know someone's notes are not good if they make them for maths... Also you can't trade/sell independent/CSSA/NEAP it's illegal.

Re: HSC 2016 2U Marathon

Notes for maths means that you wear raincoats in showers.
I think notes would still be useful for revision. Obviously 100% reliance on them wouldn't be efficient but it's not counter-productive (if that's what you're suggesting).
