Hello everyone, I have just created my account here and so this is my first post and I would like to appologise if my question may have been posted by someone else. I am new to mathematica but I am very found of the program. So much so that I am trying to use it for one of my research projects as an alternative for mathcad which I've been using for many years and with many frustrations. I have managed to work my way through functions and what not (I am still learning) but at the moment I've reached a delicate problem. I have this single variable function which has many roots and I would like to know how can I find them all. I can use FindRoot and get one root at the time given I chose the proper starting value. But is there a way I can tell mathematica to find, for exemple, the first 5 or 10 roots? As I said I am quite knew to Mathematica so this question might sound silly but any help would be much appreciated.
