Eeeeeeeeexactly. :P

L'H is mostly abused by Ext 2 students only. It's never really been necessary in Ext 1

Wow! Thank you all for the swift replies :p Will definitely be posting more.

Can't agree more. It's actually reached a ridiculous point where marks are being deducted for not stating that a pair of supplementary angles lie on a straight line xD

I think the hardest part of HSC maths is how you format your working. Sometimes rough doesn't cut it :/ unless you're desperately scraping for marks

Haha! It's absolutely not xD I think my original intention was to post an inequality. Awkward but oh well

This inequality is very famous. See the proof on Wikipedia. Come back if a step doesn't make sense
