limit()
there are unique limits that it cannot determine. If
expression1
than
var
obtain a more concise result.
Limits can be very sensitive to rounding error.
When possible, avoid the
Exact/Approx
when computing limits. Otherwise, limits that
should be zero or have infinite magnitude
probably will not, and limits that should have
finite non-zero magnitude might not.
