Man, glad that test is over.
I nearly cried at the rollercoaster question.
Lmao q7-10 was piss easy compared to that.
Anyways mark for band 6?
Around 80-83%?
think of it like sin 2x
the 2 is the number of times a period is completed..
so in the equation a is the period.
Then you can see where im coming from.
I dont want some bullcrap similar triangles thing like last year u needed to work out the Area.. piss me off.
Def would love a trig or geo Q10. So i can dominate Zak ;)
