anonymous · Answer

a ∈ S means a is an element of the set S;[6] a ∉ S means a is not an element of S

anonymous · Answer

Oh ok. So if it says $$x, y, z \in  Z$$, then it means that x, y, and z are elements of set Z?

anonymous · Answer

yes Im guessing x,y,z would be a 3d coord

anonymous · Answer

What class are you in that you are seeing this? pre calc, calc??

anonymous · Answer

This is in pre-calc, but I'm just getting a feel for what it'll be like. I have seen this in algebra II and geometry before though, so I was wondering what it meant...

anonymous · Answer

well for example, if you have a set [x,y] you are saying that in this interval x,y..x and y are included where as (x,y)..x and y are not included..so u could use the notation to say c ∈ (x,y),...c can be found in the interval x,y where x and y are not included

Oh ok. Thank you :)
