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).
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.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.
Very much thanks to you. I can churn out the questions, but I am quite careless sometimes with details.The Ext1 paper should be free of typos now...
This!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.
A question asked far too often at school.Do we need to bring our own paper?
This!
I'm defs not doing the paper - I know like 35% of the content lol.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
1. Yep.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?
Ok cool.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)1. Yep.
2. I'll be marking the papers immediately.
Use PM.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...
Sure thing.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.
You don't need to bring paper, because of this:Do we need to bring our own paper?
This!
Around a week maybe. But then there's MX2 so maybe 2.Ok cool.
