The stability properties of the method discussed. Some numerical test, reported to show efficiency and accuracy of our newly developed method.en-USEfficient implementation of Some Block Extended Trapezoidal rule of first kind (ETRs) class of method Applied to First Order Initial Value Problems of Differential EquationsArticle
