for part b is the expression inside the brackets supposed to be:

4x^4-4x^2+1?

because I cant get 4x^2-4x+1, and I enter cos(2pi/5) into both sides of calculator and I get different answers.

Working out

The Ext1 paper should be free of typos now...

 

[Carrotsticks]

Carrot, I think there is a mistake part b). If you solve the quadratic for x=cos(2pi/5) i.e. solve 8x^2-9x+1=0 the solutions are 1 and 1/8, neither of which is the value of cos(2pi/5).

for part b is the expression inside the brackets supposed to be:

4x^4-4x^2+1?

Yep you two are correct. I think in the excitement of realising that it was actually a quadratic, I typed it as a quadratic, when it was in fact a quartic hidden as one. Kinda gave it away though, with that typo.

The Ext1 paper should be free of typos now...

Very much thanks to you. I can churn out the questions, but I am quite careless sometimes with details.

Without Trebla, the paper would not be how it currently stands. Note that the questions I'm throwing up here are just drafts. I think of the question, then quickly type it down without having it checked thoroughly.

The actual paper has been checked and re-drafted at least 10 times already.

 

[math man]

this looks good, count me in for the test, ill be there early. I'll be hoping for 85+.
Do we get scaling?

 

[seanieg89]

Hey carrot, didn't get a chance to go through the mx2 thoroughly as I planned to, are you happy with how it is now?

 

[Carrotsticks]

Okay so the event begins tomorrow! I will stick signs leading to the Examination Room, where you will be completing it.

Printing will be tough, a LOT of pages.

 

[twinklegal19]

the printing will be "tough"?

think of the poor students being annihilated by the paper tmr

 

[seanieg89]

Final copy + solutions near ready carrot?

Re: The p00n thread

also carrot, after the exams, will you be able to post like averages and question averages so people can see their strong and weak points.

Do we need to bring our own paper?

This!

A question asked far too often at school.

 

[deswa1]

Re: The p00n thread

Two quick questions:

1. Is there free internet at Parra library?
2. Are you guys planning on staying back for lunch and stuff after the test?

Re: The p00n thread

Of course brah. Are you sitting the paper or just coming anyway?

And there's only meant to be 4 of us (1 Greek=me and 3 Egyptians) but there's a 5th guy as well

I'm defs not doing the paper - I know like 35% of the content lol.

Probs just work on Eco and chill at Parra Library.

How long do you reckon it'll take to get the results (not rushing you lol- take your time)

Re: The p00n thread

Why did you move it to the other thread???

I don't want to others to know if we're meeting up before/after the meat...

Use PM.

 

[Demento1]

Really wish I could come to the meat and see Carrot's 'golden' paper (seems almost AMC like). @Carrot- Will you be able to post the exam papers when you're through with the marking? I'm just interested to see the sort of questions you're throwing.

Sure thing.

This!

You don't need to bring paper, because of this:

Ok cool.

Around a week maybe. But then there's MX2 so maybe 2.

 

[dawooddaman]

Let us know if iSplicer is going to attend

Plus if this kid "theind1996" can attend that will be great
