@givingupfr It was on a practically identical past paper question and they wanted soot as the main answer, not sure whether the mark scheme accepted copper oxide

@ihatetoastt @1jamest11 @Shehantbh You would probably lose like 2 marks one for the wrong answer and one for messing up one step.

@chillerman335 @1jamest11 @Shehantbh Hahaha u seem smart- I think I just made silly mistake subsituting the k and m value back into the vector things- how many marks do you reckon I would still get? Do u think more like 2 or more like 3?

@chillerman335 @1jamest11 @Shehantbh Also what were the answers for the trigonometric graph questions they confused me lol

@chillerman335 @ihatetoastt @Shehantbh Do u think it could be 3 marks
1 for working out vector AB
1 for working out OP
1 for working out OQ

@1jamest11 @ihatetoastt @Shehantbh Yep that would make it wrong. You will still get a couple marks for working though

@chillerman335 @ihatetoastt @Shehantbh Yh for the first few lines I did the same
I only used one variable which was k that's where I went wrong
