That should scale to ~90 IF you look at the raw marks database, please note scaling can differ year to yeargot about 83 raw
what does that scale to ?
Well, that implies it so I doubt it.other than that everything looks good i think.
would i lose a mark for not writing the units in 12a)ii) ?
and in part 13ciii (parametrics), i only stated that y =/= 2a, i didn't say x =/= 0. would i lose a mark for this?
nah because i didn't say y =/= 0 so it's not quite the same thing, it's like half the restrictionWell, that implies it so I doubt it.
Ah, I see what you mean. I still doubt it though because if they wanted you to say that I think they would've asked something like 'describe the locus' to fk people over.nah because i didn't say y =/= 0 so it's not quite the same thing, it's like half the restriction

Difficult to say for this one because there are so many different methods.What would you expect marks to be allocated to for Q13 c) iii)?
I doubt you would lose a mark for that restriction.hmm so for the circle locus question (13 c. iii.) is the restriction on the locus x=/=0 ? if yes, would we lose a mark for not putting that restriction even if we got the equation of the circle?
100% then.No, you won't lose marks for not writing the units.
For the condition, you won't lose marks because you've shown what the Q has asked for, whihc is that Q lies on a fixed circle of radius a.

I doubt you would lose a mark for that restriction.
Is this 'other method' braintic's solution or subbing coordinates directly into the equation of the circle/showing SQ=a?Trying to cram the other method of doing the locus problem into the gap on page 10, fingers crossed that it can fit!
No, you would not.just wondering out of curiosity, for the rainy day question would you lose the mark if you put 30c1 instead of 30c29? they're the same thing anywayso....

thanks heaps thenNo, you would not.
It was along the same lines as braintic's method. I added a bit more justification because students often don't understand geometric arguments for solving loci problems.Is this 'other method' braintic's solution or subbing coordinates directly into the equation of the circle/showing SQ=a?
