[Sien]

People on the confessions thread talk about vehicles and use the term MX5...

That automagically registers in my head as Mathematics Extension V.

._.

save my soul pls

What soul
Haha

MX∞

But ∞ is not a natural...

k I'll stop now.

um.

are you trying to say something here?

you could be more direct you know...



I kid.

I totally used pseudo-"inspection" to save time on 4U today.

It was one of those "Hence prove the the point T is T(..., ...)" which is done through simultaneous equations

I solved for y simultaneously, then just said "Substituting this back into the first equation gives x = [xcoord from question]" rather than actually dealing with the equation twice

i do that in 2U lel

usually I consider the quotient and product of the x y co-ordinates... That's most of the "hard" locus questions.

The rest are impossible to see (and hence require magic) and the remaining are usually so obvious that the question can be handwaved in one line.

Oh no it was heaps easy, it's was just to prove that the coordinates were something. I think it was T(2cpq/(p+q), 2c/(p+q)). It was the point of intersection of the tangents at two points on a rectangular hyperbola. In the next part pq was assumed to be some constant (C) and so the locus is y = x/C

Curious: can I use matrices to solve simultaneous equations in my 2u exam? lel

that's so easy I laugh.

LOL

I know you can use Matrices to solve problems of the Conic sections in 4U (source: Olympiad tutor)

I'm not sure 2U affords students the same flexibility.

Wow gees your simultaneous equations in 2U aren't even hard and you want matrices?!

Are you sure you're allowed to use matrices for the Conics section in HSC? Because that'll really trivialise some of the questions they ask.

for the lols
Plus 3 sim equations..matrices is so much easier legit

SCREAMS

WHAT

That's so much easier I'm literally sobbing inside I wish I knew this eariler

Only for the actual HSC. No idea what your school demands of you.
