This is not homework but a problem I would like to learn to solve before my exam. 1. The problem statement, all variables and given/known data https://dl.dropbox.com/u/23889576/Screenshots/01.png [Broken] 2. Relevant equations Series Formulae 3. The attempt at a solution I went about trying to determine a sum formula for the fly's distance travelled but could not get very far. Any help available would be appreciated. Thanks in advance.
