Right, you could use a Newton method to do this. > Or did you mean that there is an easier way to write such an algorithm > with scipy? No, I don't think it is easier, or harder. I think the difficulties are approximately similar. I was just wondering what where the pros and cons. I sum up the pros for sympy, according to your mail: possible exact expressions, and better precision. I suspect in the case of non-exact expressions, it may be slower.
