Homework Equations
The Attempt at a Solution
This isn't a homework question per se (and I'm not that interested in the actual number solution), but how would one go about solving v? Are there any general tricks? I tried searching online, but all I could find are ways to prove that it converges -- not that how to find the actual converging value. It easy to see that it converges, just having a little trouble finding out to what value it does.
