I would have thought the head examiner would have used the 'hence' method for the locus question.

 

[Gumball]

well technically he kind of did. using the hence method would get you an equation like the answers did. more people didnt use the hence method and talked about it graphically

Really? Where did he use the fact that the gradient of OQ is t?

woops my bad. but other people used y/x=t which is using the previous part

Haha, no I'm not. I'm just a Maths teacher that likes to keep my finger on the pulse with regard to the Maths curriculum, particularly senior years. If I get the time I like to write my own solutions for papers and create new questions to use for my own assessments.

I find it kind of interesting that someone would claim I am the head marker though. Not sure where that came from.

Gumball was claiming he was your child..... :/

Afraid not, don't think I'm old enough to have a child doing the HSC!
