The problem of approximate quadrature is one of the most studied problems in analysis. Emerging from the needs of computations associated with the solution of various applied problems, it has been extensively developed and has been the subject of numerous studies. The works in this field are exhaustive, but the study of the outside world poses new problems where seemingly everything is known. An example is the approximate quadrature formula for a complex function F(y₁, . . . , y_n)...
