Good afternoon.
I'm brazilian, then sorry by my bad english. I have a problem with one question about Infinite Series.
I searched for anyone method could help me. I have all constants values (w, y, z, h, a). But I don't know what do. Someone can help me? Giving me one way is enough.
Thanks a lot!
\begin{align} &\sum_{n=1}^\infty \left( \frac{e^{-\alpha R_n}}{R_n} + \frac{e^{-\alpha R'_n}}{R'_n}\right) \\ R_n &= \sqrt{w^2+y^2+(2nh-z)^2} \\ R'_n &= \sqrt{w^2+y^2+(2nh+z)^2} \\ h &= \text{thickness} \end{align}
