Any schools teach perms and combs in year 11 (2 Viewers)

[DatAtarLyfe]

Our school did perms and combs in year 11 as well.

2u: algebra and arithmetic, functions, trig
3u: further algebra and functions and inequalities, quadratics reducible to equations, rational functions, trig

Why the fck do ur 3u topics look dodgy af?
We did circle geo first and pree much scared off half the class

They taught you circle geometry before they taught you how to do 4/(x+3)<2?

ooh I know this
you have to multiply both sides by (x+3)^2, because you don't know the sign of the expression

With the appropriate setup, I could disguise you as a 4U student.

"hard" factorising?

What is this foreign concept you speak of.

I would say that factorising can become quite hard especially when you start looking at Galois Theory.

3u student

Don't even need to, just take x=-3 as one point, and solve the inequality as an equality.

Any schools teach induction in yr 11?

We're talking about elementary factorisation though.... -.-

does it count if I self teach

 

[eyeseeyou]

No, if your school teaches it

I believe speed6 learnt it in year 11

 

[Green Yoda]

I believe speed6 learnt it in year 11

some schools do series(2u topic) in yr 11 and Induction(3u topic) goes really good with it.

 

[si2136]

I believe Baulko has done it already. And my school is doing it in around a few weeks for the normal Yr 11.

 

[k_2017]

Mine did it almost first up in Term 1

I hate the name "Perms and Combs" for this topic, for two reasons:

(1) It suggest that all counting is done using just these two techniques

(2) It sounds like a hairdressing course

lol really. It's a shortened way of saying "permutation and combination"

But it sounds better short than long

Mine did as well. And that's how a lot of people ended up dropping 3U

lmao how many?

Bro look at yr 11 3u Cambridge extension questions. If you say they're easy at the beginning of year 11, you're arrogant af.

Maybe if you're Margaret grove and teach at Bankstown tafe.
