    initially i was giving a question for TeeEm since he was interested, but i decided to read through the relevant chapter so it will probably turn into to former very soon

    I remember one of the geniuses on here post something similar before...
    For 14, does  \displaystyle \frac{1}{3}\left(\exp(z) +\exp(\omega z) +\exp(\omega^2z)\right) make any sense? Oh, and take the real part.
    I suppose you can generalize and sub z = 1 for 15.

    Yeah that is answer for the first part,there is also the summation of the series though

    I'm supposing the method is sub z = exp(iθ), and take real part.
    \displaystyle \frac{1}{3} \left( \exp( \cos(\theta) ) \times \cos(\sin(\theta)) + \exp( \cos(\theta+\frac{2 \pi}{3})) \times \cos( \sin(\theta + \frac{2 \pi}{3})) + \exp( \cos(\theta+\frac{4 \pi}{3})) \times \cos( \sin(\theta + \frac{4 \pi}{3})\right)
