Through utilizing this approach, the proposed equations reduce to a system of algebric equations with unknown Bernouli coefficients. A number of numerical ‎illustrations‎ have been ‎solved‎ to ‎assert‎ the ‎credibility‎ and ‎practically‎ of ‎this‎ ‎method SP - 19 EP - 32 AU - Matinfar, Mashallah AU - Abdollahi Lashaki, Hamideh AU - Akbari, Mojgan AD - KW - ‎ ‎I‎ntegro-differential equations KW - ‎Bernouli‎ polynomials KW - Operational matrix‎.
