The correct answer is of course IND -- the limit set is [0,%pi/2). Presumably what is happening here is that there is an intermediate calculation of limit(tan(x)^2,x,inf). ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=659288&group_id=4933 ```

Of course, one-arg limit is not advertised to work with UND, but internally it seems likely that this is what it is doing. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=659288&group_id=4933 ```
