What do these weird square brackets mean? [| |]
In my BC Calc summer homework (taking the course next school year), I came across these odd square brackets in a limit problem and have no clue what they mean. I've looked all over the internet and cannot find anything similar. They're like [] but have two vertical lines on each bracket instead of the just one.
this is the best representation I can give:
[| x - 1|]
The problem is this:
lim [| x - 1 |]
x -> 4
N/A
For now I just kind of ignored the brackets and just plugged in 4 for x and got 3.
Please help! I am thoroughly confused and extensively frustrated. >=(
