A collocation procedure is developed for the linear and nonlinear Fredholm and Volterra
integro-differential equations, using the globally defined B-spline and auxiliary basis functions.The solution
is collocated by cubic B-spline and the integrand is approximated by the Newton-Cotes formula.
The error analysis of proposed numerical method is studied theoretically. Numerical results are given to
illustrate the efficiency of the proposed method which shows that our method can be applied for large
values of N. The results are compared with the results obtained by other methods to illustrate the accuracy
and the implementation of our method.
