# What is this operator?

1. The problem statement, all variables and given/known data

the limit of [theta] / theta

as theta goes to 3 from the left hand side

The brackets though, are only the bottom half of a bracket, like an L and the mirror image of an L around the theta. The solution manual shows the answer is 2/3. I'm really quite confused on what the half bracket operator could be. Thanks in advance.

It's the floor function. It means that you round down to the closest whole number.

So for example floor(9.6) would be rounded down to 9.

Uh, aren't ceil and floor different? You defined one and then used the other in your example. Sorry to nitpick. :)
