Keywords: General purpose, Convolution sums, Chebyshev series, Fourier series, Function.
Classification: 4.6, 4.7.

Nature of problem:
Numerical calculation of the coefficients for a single series obtained as the product of two series.

Solution method:
Application of standard results for Chebyshev Polynomials and Fourier Series.

Length of the series is not limited in the subroutine package but is limited to 41 terms in the main driver, I/O and test programs.

Running time:
Dependent on required range and accuracy: for the test cases it is 0.15 seconds.
