Let ∈ < 0.
[Don't worry about it if you don't get it]
"In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..."
We should probably be worrying more if we do get it.
Why did the vector cross the road?
It wanted to be normal.
not understand......can u explain?
In dealing with limits, sets, and sequences, just about every single proof starts off with the line:
Let ∈ > 0.
It reached a point where ∈ is pretty much just assumed to be a positive real number.
