Thanks Stroodle! So I was right about the simultaneous functions.... lol

[Ilovemathsmeth]

With the number set {x:|x-1|less that or equal to 4}, I cannot figure out the interval notation.

Essentials is useless at this explanation lol

Sigh... I swear Essentials does the shittest job of explaining modulus..

Nuu don't bag my precious Essentials =X

Much as I agree that they explained the modulus function VERY poorly and that I had to sit and analyse the theory for ages on my own, Essentials is an awesome text book =D I <3 it.

Essentials is great! Much better than MathQuest...

Yeh, Essentials is the best!
A friend of mine gave me an old Essentials MM 1+2 textbook when I was in yr 8 or something.
Anyway, I had a read through some of the chapters and found it really easy to understand.
It's great for trying to understand new concepts!

Let f: R → R, e^{–x}
For all u ∈ R, is equal to
A. f(u) + f(–u)
B.
C. (f(u))^2 – 2
D.
E.

Can somebody explain to me how this is completed? iTute don't have the solutions to the CAS papers for the last couple of years and this is a question which was only on the CAS paper.

Thanks guys

Then just check each of the possibilities to see which matches:

A: nope
B: nope
C: YES

Thanks /0! I also tried using the CAS calculator but i got ... whatever cosh is!

You don't need to know it for vce, but just in case you see it on your calculator,

Thanks! I might chuck it in my reference just in case it comes up again

Quite a few people got confused by this in our tech-active SAC on Thursday

We did this two weeks ago in MUEP
