Speaking of which, I just figured out that to use complex bases and
exponents you can convert the rectangular vector (a+bi) to circular
(ai^b) and then you only have one term and it becomes (somewhat) doable!
Mind you that I have never had this sort of material in school, I
conjecture it playing with my TI-89. :) So now I know that n^i =
cos(ln(n))+i*sin(ln(n)), but I have no idea why. :)
