What does this mean when talking about suitable domains?
>>
>>7763411
It means x is real.
>>
>>7763411
x = variable x
∈ = 'is an element of'
R = real number set
Hence, x∈R is simply a small note stating that x is a real number.
>>
>>7763412
So how big do I need to make this graph?
>>
>>7763417
not that big, just - to + infinity
>>
>>7763411
It means x is not fake
>>
>>7763571
u mean 'irrational'
>>
>>7763771
Irrational numbers are still real. They're literally between reals
>>
>>7763411
X is an element of the real numbers

Here, have a video:

It means your 'x's cameltoe is real.
>>
can't you read the picture? it says

boobs, vagina, penor in hole
>>
>>7763775
You mean rationals?
>>
>>7763818
>>7763818
Yes. I am an idiot and English is not my first language
>>
>>7763818
>>7763827
they are between reals as well ;^)
>>
>>7763831
>>7763818
>>7763771
Stop being so irrational
>>
It means x is not imaginary, in which case you'd need another dimension to your graph.
>>
>>7763422
>>7763417
Just scale your axis by the tan(x) and you only have to draw from -pi/2 to +pi/2
