摘要：
In this article we construct boolean cubature formulas using univariate Lagrange interpolation projectors with Chebyshev nodes of second type. We compute the coefficients of these cubature formulas using coefficients of corresponding Fejer-Clenshaw-Curtis quadratures. The remainder terms have minim properties in a class of cubature formulas with the same number of nodes. Some numerical examples are given.
