I ment of course that i'd like Mathematica to give me ALL the roots on form: angle + (period * n). I'll try to be more exact the next time. > Didn't you notice Mathematica's comment that, since inverse functions were > being used, some solutions might not be found? That's the explanation. Yes, i did. I wonder why it's the ONLY method used by Mathematica. It feels pretty bad to know that the program "misses" some simple roots. I don't wonder "what kind of algorithm gave that", rather "why do they use only that algorithm". I appologize if my question caused any trouble by it's "fuzziness". -- Vänligen Konrad -------------------
