if there's combs best belive that shit is getting left blank and omd if I see a geometric induction oml its done

Yeah facts bro for all the rlly hard induction tho just do the base case and assumption so u get a mark or two and then come back to it later imo

 

[nad1231231]

who even wants an e4? i reject the e4 bfr the e4 rejects me preach

I feel like a lotta people can get it u probs can just try do as much of 11-14 as possible and try ur best not to do silly mistakes and then just scrounge marks from the hard shit

 

[I Love maths So much]

HELP i thought 3 was enough. damn u rich to buy that many

I just find them around school I have only bought one.

Good luck everyone signing off for the evening, see you all hopefully on tomorrow's livestream approx 6pm! (on the same YT as account name).

 

[zachyboi525]

first of, no u didn't lil bro and secondly I got an easy 100 on that paper in my sleep. Step it up

You better get a higher state rank than me then buddy or you just lying straight up

i was watching ur videos earlier and ur commentary was so funny, didn't know i could laugh while watching a math video

Is not doing question 16 a conceivable strategy

q16 overrated in the sense in that, the easiest qn on q16 prob isn't harder than the hardest qn on q14,15, thus you could just scrape marks off those instead

Good luck everyone!

should be easy to get a higher state rank than someone who isn't getting one . dw easy 1st place in 4u for me today

on EVERYBODY'S SOUL there will be fallacious proofs today

Actually, the word "plane" is used everywhere in HSC Maths e.g. "complex plane", "x-y plane" or "inclined plane". It's even in one of the vector topic dot points:
View attachment 45037
Seems pretty obvious that students are expected to know what the word "plane" actually means.

Even if they don't explicitly use the word "plane" there is no reason why they can't just synonymously label it as a region or a set of points in the number space that satisfies a set of conditions.

What I mean in my earlier post is that there is nothing stopping them technically asking something like this:
View attachment 45039

If we honestly think they can't use the word "plane", then what's stopping them replacing the word "plane P" with "region R" or "a set of points P"?

The point is that students can answer this question with the tools they have within the syllabus and it doesn't require knowledge outside the syllabus (i.e. notice it's not asking you to recall the equation of a plane). All you need to do is compute the dot product of two perpendicular vectors (with a bit of work to figure out what those vectors are) to derive the result. This is simply an "application" of something in the syllabus to explore something unfamilar.

If you want to dismiss this as being "outside of syllabus", then you do so at your own risk. The HSC exams have time and time again proven otherwise throughout history because they can sneakily lean on this "application" side of the syllabus (which is why Ext2 has this reputation for being so challenging in the first place).

I emailed NESA about this a while ago and they explicitly said "The equation of a plane is not part of syllabus content however students need to have a conceptual understanding of the nature of a plane." and provided the exact same dot point that you provided.

But I think NESA most likely won't ask this anyway, because while some students may be able to guess the procedure here, students don't really know what they're dealing with when they see an equation such as x-z=1. How would they know that this procedure correctly maps all the points on the plane to that Cartesian equation, or whether the plane is possibly a subset of that Cartesian equation or vice versa? And what exactly is the meaning of something like x-z=1 for somebody that has not studied planes besides simply using the result algebraically?

I think NESA would be more creative and would prefer to write something that wouldn't provide a significant advantage to particular students, such as those who have studied and understand the Cartesian equation of a plane. Similar to how proponents of learning the cross product have not been able to actually use it in any exam.

gl everyone lock tf in it’s maths season babbyyy

I think there will be a difficult mechanics pulley or pendulum question in 15 or 16

Just over 3hrs to go, still time for one last paper

I hope not thats like my worst bit in the whole course

bad idea to do one last paper now. Just chill til the exam

yeah i know im not actually doing one
