Just a few things that I've been thinking about lately: Are there any taylor/power series that converge to logarithmic functions (f(x)=log(x), etc.)? How would you do this? Is there any series that will graph the traditional bell curve? How would you do this? I remember the derivation of "e^[i(pi)] = -1" involved a series that converged to e. What series was that again? Thanks.
