Dear Arie, I wonder if you or anyone else would be interested in making the reduced form more explicit. The two pi seem to come from thin a bit and don't really explain the step(s) involved. Kind regards Paul Anand p.anand@open.ac.uk
It just doesn't seem to make sense to post a random link like this. If you feel it belongs in this article, please explain yourself. Thanks. Dj stone ( talk) 03:43, 14 May 2008 (UTC)
Hello Arie. I don't think it is possible to use self-published materials in wikipedia. For more information, you can read http://en.wikipedia.org/wiki/Wikipedia:Verifiability#Self-published_sources_.28online_and_paper.29 - Pergamino ( talk) 00:15, 22 May 2009 (UTC)
Welcome to Wikipedia and thank you for
your contributions. I am glad to see that you are discussing a topic. However, as a
general rule, talk pages such as
Talk:Elastic collision are for discussion related to improving (a) an encyclopedia article in specific ways based on
reliable sources or (b) project
policies and guidelines. They are
not for general discussion about the article topic or unrelated topics, or statements based on your thoughts or feelings. If you have specific questions about certain topics, consider visiting
our reference desk and asking them there instead of on article talk pages. Thank you. -

Note: we are of course allowed to discuss it here in user talk space.
We don't even need L'Hopital. Merely factoring out a c^2 factor from numerator and denominator and simplifying, the limit immediately follows. - DVdm ( talk) 11:16, 14 December 2020 (UTC)
