摘要：
In this paper we introduce an integration method with equal coefficient in the following form: integral(b)(a) w(x)f(x)dx similar or equal to C-n Sigma(n)(i=1) f (x(i)). Then by using the formulas of Newton's equations and degree of precision we introduce a method which express the nodes and coefficients in this integration formulas. Finally some examples are presented to illustrate the procedure. (c) 2006 Published by Elsevier Inc.
