Lim as x approaches 4 of 1/x = 1/4 Given epsilon > 0, come up with a delta, d? Limits have been introduced. So far my instructor has had us make tables to see what value x was approaching. Although I don't understand exactly how limits are EVALUATED (different from looking at a chart & saying "yeah, it looks like it's approaching 4 or whatever", it's pretty clear & makes intuitive sense. Anyways, I've never seen a problem like this before. Can someone please walk me through this. I have no idea where to start. The limit has already been solved... epsilon is any small number, right? And delta is simply a difference?
