Plotting a procedure is this possible?

Greetings All

I’ve worked out a Fourier Series Expansion using excel and verified it by graphing it in excel to check my results.  See example

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 Maple 11.  I’ve included an
