The numerical methods consider are standard collocation and perturbed collocatio methods using shifted chebyshev polynomial as basis function. The result obtained shows tha perturbed collocation method proved to have a better approximation than that of standarc collocation methods in the cases considered. Three examples are considered to illustrat efficiency method.enArticle
