This is a good idea. Having difficulty 'levels' when posting up questions is a good way to cater for different skill levels on the forums.Level I
Level II
Level III
TBA tomorrow when I am bothered.
It's always black when it comes to negative. =.=This is a good idea. Having difficulty 'levels' when posting up questions is a good way to cater for different skill levels on the forums.
However, I suggest you co-ordinate the colours with the level of difficulty.
ie: Green = Easy, Blue = Medium, Red = Hard.
Black = Destroy.
Because nobody can read white.^I know right...why can't it be white?
Preuni question?This is a bit of a tricky question.
However looking at the quality of the questions and solutions so far, I'm quite convinced that one of ther 2012'ers will get it:
Do you go to Pre Uni?Preuni question?
Hahahaha. That made LOL. Owned himThe 'little circle' is the universal symbol for 'function composition'.
Guess I'll contribute a question as well..
= (1 - w)(1 - w^2)(1 - w)(1 - w^2)n=6 (assuming n=0 isn't allowed).
Given that w is the complex root of z^3=1 with smallest positive argument, evaluate:
(1-w)(1-w^2)(1-w^4)(1-w^8)
Is this a past HSC question? I remember doing this exact question about two days ago. I'll let someone else post a solution though.
Question
No, it's 8.yeh its 9.
And that's a magic number.....No, it's 8.
No, it's 9.
Yes, that's right, I was testing you. It's 9.
Yeah it is a past HSC question.Is this a past HSC question? I remember doing this exact question about two days ago. I'll let someone else post a solution though.
With your previous post, the answer is a nice integer. You made a mistake in the second line where you changed (1-w)(1-w)(1-w^2)^2 into (1-w^2)^3
