1. The problem statement, all variables and given/known data for some potential problem, and after using separation of variables 2. Relevant equations V(x,y) = 4V0/∏ Ʃn=1,3,5... 1/n e-n∏x/a sin(n∏y/a) (1) ,where V0 is some specified reference potential and a ε ℝ which can be summed explicitly to: v(x,y) = 2V0/∏ tan-1(sin(∏y/a)/sinh(∏y/a) (2) 3. The attempt at a solution I've been out of school for a while, so I don't recall my calculus as best as I should? What transform / series would I use for getting from (1) to (2)? No need to spend your time on the gruesome details (leave some fun), but can anyone point me in a general direction?
