Best ResponseYou've already chosen the best response.0what does \[\eta\] stand for?

anonymous

Best ResponseYou've already chosen the best response.0oh maybe \[\mathbb N \cap \mathbb R\]

Best ResponseYou've already chosen the best response.0Yes it shows it like that except the U is facing up? And how did you post them like that i was looking for them.

anonymous

Best ResponseYou've already chosen the best response.0\[\mathbb N \cap \mathbb R=\mathbb N\] since the natural numbers live inside the real numbers and \[\mathbb N \cup \mathbb R=\mathbb R\] for the same reason

Best ResponseYou've already chosen the best response.0Oh thanks and sorry i am sorta new to this site so don't know exactly how to post stuff correctly.

Best ResponseYou've already chosen the best response.0that is ok, easier just to describe the symbol pallet is only good for some things. i was showing off in latex

anonymous

Best ResponseYou've already chosen the best response.0Oh what is latex? And how do i post and upside down unison like you did?

Best ResponseYou've already chosen the best response.0if you want to see any code, right click and it will show up. you can also copy and paste

Best ResponseYou've already chosen the best response.0Oh do i just click show format or what?\[\left[ 2,\infty)\cap(4,7)\cap(3,2 \right]\]

Best ResponseYou've already chosen the best response.0this is my next problem ^

Best ResponseYou've already chosen the best response.0so you are looking for what is in common to all three intervals. easy if you drew them

Best ResponseYou've already chosen the best response.0the only number that \[[2,\infty)\] and \[(3,2]\] have in common is 2

anonymous

Best ResponseYou've already chosen the best response.0so that is the only number in the intersection

anonymous

Best ResponseYou've already chosen the best response.0It says simplify the unions and intersections of intervals.

anonymous

Best ResponseYou've already chosen the best response.0yes your answer is just one number: 2

anonymous

Best ResponseYou've already chosen the best response.0Oh well that was simple so it is just what they have in common?

anonymous

Best ResponseYou've already chosen the best response.0yeah intersection mean in both

Best ResponseYou've already chosen the best response.0\[(4.8,3.5)\cap \mathbb{Z}^+\]

anonymous

Best ResponseYou've already chosen the best response.0this is last problem of these kind... don't mind + above Z it should just be Z

Best ResponseYou've already chosen the best response.0do you know what \[\mathbb Z^+\] is? (nice looking isn't it?)

anonymous
 4 years ago
Best ResponseYou've already chosen the best response.0ah that is different. \[\mathbb Z\] is all integers \[\{...,3,2,1,0,1,2,3,...\}\]

Best ResponseYou've already chosen the best response.0In my book it stands for set of all integers.

anonymous
 4 years ago
Best ResponseYou've already chosen the best response.0so you are looking for all integers in the interval you have. how many are there?

anonymous
 4 years ago
Best ResponseYou've already chosen the best response.0i think only one in there is 4

anonymous

Best ResponseYou've already chosen the best response.0Only one integer correct.

anonymous

Best ResponseYou've already chosen the best response.0then that is the only one in the intersection
