Can anyone explain to me why the exponential function maps the strip { $\displaystyle z$ $\displaystyle \epsilon$ $\displaystyle \mathbb{C}$ : - $\displaystyle \Pi $$\displaystyle /$ $\displaystyle 2$ $\displaystyle <$ Im$\displaystyle z$ $\displaystyle <$ $\displaystyle \Pi$ $\displaystyle /$ $\displaystyle 2$ } onto the RHP? Thanks!!
