Mathematical modelling of real-life problems normally outcomes in functional
equations, like ordinary or partial dierential equations, integral and integro-
dierential equations, stochastic equations. Numerous mathematical formula-
tion of physical phenomena be composed of integro-dierential equations, these
equations originates in many elds like
uid dynamics, biological models and
chemical kinetics. A. Bellour and M. Bousselsal [1] discovered the numerical
solution of delay integro-dierential equations. The main purpose of their work
is to provide a new numerical approach based on the use of continuous colloca-
tion Taylor polynomials for the numerical solution of delay integro-dierential equations. In this paper, we study the integro-dierential equations with a
bulge function. The solution is derived by using Laplace transform, inverse
Laplace transform, the convolution theorem and the Taylor series expansion.
The numerical solution is obtained by the trapezoidal rule [4].
