Annoying pedantry, (but fitting for HN), calculators are actually a very nice tool for initiating students onto the idea of a limit by having them calculate closer and closer values to a limit that can't be evaluated on the point. Of course, analysis fundamentally is about just that, approximation in calculations although people don't manually calculate derivatives or the like today.
