International Journal of Engineering and Information Systems (IJEAIS)   Year: 2023 | Volume: 7 | Issue: 7 | Page No.: 44-50 A numerical method for calculating triple integrals numerically when the value of the integrals is not defined at the upper limit of the integral Download PDF Lecturer.Rana Hassan hilal abdolah Abstract: "The main objective of this study is to derive a new rule numerically for finding triple integrals when the value of the integrality is not defined at the upper limit of the integralwhen by using Mid-point rule on the x and y and tripsinol rule dimensions z and how to find the correction terms (error formula) and we use Romberg acceleration""to improve the results when the number of subintervals of on the three dimensions are equal".
