Math problem Created 13 years ago2011-03-27 17:33:12 UTC by Striker

I request some help, please, but only from those who are good at maths.You are given the above matrix, and the "crowd"(really, have no idea what's the term in english) "M" composed from A to the k matrix(es?).
The problem asks how many elements M has.

I don't know how to solve the problem, so I was just guessing it might be infinity, since dividing pi with a value that gets higher and higher, you'll only get values that get closer and closer to 0( this is not a limit so I'm not discussing about dividing a value to infinity, which is 0). That means that every number is valid. Whatever, not that I am so sure about this part anyway.

Things get complicated when I see that k belongs to Z, and when trying to visualize matrix(es?) raised to a negative power(sincerely I think I am awfully failing at math at this point) it makes my mind explode.
But the problem correct answer is 2n, and I don't know why :.
Can someone explain to me ?

and the "crowd"(really, have no idea what's the term in english)

Try looking it up on Wikipedia in romanian and seeing what the english equivalent is. I'm sure that'd help the ones helping you.

This looks a bit beyond what we've been taught in matrices, but any matrix raised to a negative power would probably have to be its inverse raised to the modulus of that power.
Sorry I couldn't help any further, as I'm not sure what M is supposed to be.

And I'm trying to 'study' for attending at a politechniques university :. These are the kind of exercises you are given to resolve.

And, if I am right after searching on wikipedia, by crowd I meant a set. So M is a set.

I said already I can't see images from imageshack.

What I understand from what I read in other posts... I haven't done anything like this in 2 years so don't expect help from me anyway

I have specifically made the image a gif of 4 kb so anyone can see .

Has nothing to do with the filesize of the image, bro.

DiscoBru can't see imageshack images that have been direct linked for some reason, bunch of people have this problem, it just shows a '404 error' image.

^That. Every request from my computer gets redirected to this: http://imageshack.us/img/blocked_login.jpg

I posted a screenshot in some other thread. CBA to look it up.
