Fourier Series Expansions and it's Coefficients question revised

Greetings

I've worked through a Fourier Series Expansion and it's Coefficients and
have a better gasp at a how to explain my question.  If I'm giving a
repeating wave at (T) period of 10 seconds with amplitudes
At 14, 18.7,9,4.1,6.7,6,6.3,8.4,4,2.9 how can I find the Fourier Series
Expansions in Trigonometric form using mathematica 6.  I've included an
example that I've worked through below

I've been through mathematica site and they have examples of
Fourier Series but the examples they have are examples of equations they
give you.  I'm looking for an example where the equation isn't known and
all you're given is the waveform, repeating period in seconds and the
amplitudes. Like in my example.

Does an example exist? If not what are the steps needed in mathematica 6 to
accomplish this.

Tia simple
