[PLAIN]http://img263.imageshack.us/img263/9336/seriesgay.jpg [Broken]

In the previous part of the question we had to show where the taylor expansion comes from, and calculated the maclaurin series for e^x, sin x and cos x. From that we had to prove De Moivre's theorem and so I would imagine that these things help in the last part of this question. I can see it looks like a Maclaurin series, just not sure where to start really.

Any help would be appreciated, thanks.
