@Qiaochu: This is an interesting comment. I haven't thought about that (and I am not sure if it will help me) but it is fascinating nonetheless. Thank you.

comment Proof for law of complex exponents using only differential equation
This looks really nice - thank you! One thing I don't understand: "Using the initial condition $e^0=1$ we find that [...] Now let $z=a$" - doesn't this say that $z=a=0$ because $e^ze^{c-z}=e^c$ is only true when $z=0$?

...I read through your answer again and I think the first part will be affected by the typo but the more general and important second part shouldn't be - thank you again!
