i is the square root of -1, an "imaginary" number (although it really exists).
So, if I'm doing this correctly... would this be the solution for the exponential term?
I'm assuming that the reason why it comes out to 1 is that you ignore all of the subsequent terms becuase they would all be imaginary.

That is the same place I pulled the equation from... the check I mean. I thought it was funny and I was just curious as to what the equation actually worked out to be.
It's been about 10 years since I even had to think about calculus and advanced math, so I just couldn't remember how to work it out.
It's a shame that my engineering math just hasn't had much of a workout since I graduated.
Just for my own knowledge, in the exponential term, what is the
? I can figure out the expansion of . But I'm just not remembering what is supposed to represent.Sorry to be asking so many fundamental questions.
Thanks for the explanation!

I've been out of school too long and can't get this one...
If I remember correctly, the last term of
will work itself out to 0 as the series can be treated as a limit function. In this case, as n goes to infinity, the resulting answer is 0.I can't get the logarithmic portion though.
Many thanks for help!
