I request some help, please, but only from those who are good at maths.
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 ?
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?).
