How to think in extension 2 maths (1 Viewer)

[eyeseeyou]

So I heard extension 2 maths is all about thinking as opposed to extension 1 maths which is about "doing". Before "doing" in extension 2, you need to "think" first

Even though it's a bit early to ask this, how does one "think" in extension 2 maths?

I heard most of the time, students get tricked and end up in a traps of all sorts because they don't think thoroughly

 

[eyeseeyou]

I mean think critically

The harder questions in Ext 1 encourage that sort of approach as well (maybe to distinguish between the Ext 2 peeps and "only" Ext 1 )

And by thinking critically, for example you might have to figure out the best method or the best formula/identities , you could end up actually getting an elegant solution rather than just bashing out stuff and potentially going nowhere or getting into something really messy.

Whatever happened to that post on: Maths in Focus question on a man walking on a straight road and wanting to know the height of the tower given its angles of elevation from 2 positions ???

Sorry to insert this inquiry here!

Which forum was it in?

Really, I thought in 3U you were given everything so just use that to solve wheras in 4U you aren't therefore you need to think in order to be on the right track

You're not given all the geometry theorems and etc.

Then how do you solve it?

Then how do you solve it?

You think about the problem at hand and try to figure out a way of getting to the solution (what theories, and proofs can I use.. etc).

Actually even in 2U math has these kinds of problems.....(the last questions of course)

They just be like "prove this" without giving any hints.

But aren't there a lot more in 4U?

Just curious: What raw mark is required for a 80 hsc mark in 4u?

Looks like about 50/100.

woah really, dunno If I should be feeling good or bad cuz 93(93 raw) in 2u = 80 (50 raw) in 4u..so idk whats harder to get
