I need to find limx→∞tanxx
For some reason mathematica just returns my input without evaluating it.
For what it's worth, tan(10100)10100≈−4×10−101, so the limit is probably 0. (...)
I'm guessing this has been asked before but I can't find it.
Answer
The limit does not exist: Since the tangent function has poles at every point of the form (n+12)π, the quantity
tanxx
is unbounded on every interval of length greater than π.
