The College of Science / Mathematics Department held a training course on ordinary differential equations that do not have an analytical solution for the two lecturers, Dr. Jihan Muhammad Khudair, and the lecturer, Shatha Abdul-Hussain, the two instructors in the Mathematics Department on the Zoom platform. The course aims to introduce the study of some issues of ordinary differential equations that may not have an analytical solution and to find an integrative formula for the solution and to study its convergence to the numerical solution as the first day included introducing those equations and formulas of solutions to them and discussing anomalies and normal cases. The second is a practical programmatic implementation of these solutions
