Notation
I have a preference for the notation ln(z) for the inverse of exp(z). Is that not more common?--Paul Wormer 10:52, 29 October 2008 (UTC)
- The notation log(z) is more common in advanced mathematics. I have seen a quote to the effect that you can distinguish those that know maths by whether they use log or ln for the natural logarithm :-) But ln(z) is more common in the secondary schools (at least in my experience) and probably also in physics, and it is not ambiguous. I think that we should use ln(z), perhaps with the exception of articles on advanced (say graduate-level) mathematics. -- Jitse Niesen 13:21, 29 October 2008 (UTC)
