Dear All, Probably my question is very simple. Suppose that we have expression a= Sin[x]+Sin[y]. I would like receive variables from which this expression is dependent, so in this case {x,y}. The Variables does not work of course in this because it is not a polynomial and it gives me {Sin[x],Sin[y]}. Do anyone know how to solve my problem. I would be very grateful for quick response.
