Clenshaw-Curtis Quadrature is a numerical integration method that approximates the integral of a function using weighted sums of function values at Chebyshev nodes. This technique is particularly useful for approximating integrals over the interval [-1, 1] and is known for its efficiency and accuracy, especially when dealing with smooth functions. By leveraging Chebyshev polynomials, this method reduces the problem of numerical integration into simpler polynomial evaluations.
