Difference between Clenshaw–Curtis quadrature and Discrete cosine transform

Clenshaw–Curtis quadrature vs. Discrete cosine transform

Clenshaw–Curtis quadrature and Fejér quadrature are methods for numerical integration, or "quadrature", that are based on an expansion of the integrand in terms of Chebyshev polynomials. A discrete cosine transform (DCT) expresses a finite sequence of data points in terms of a sum of cosine functions oscillating at different frequencies.
