The overall goal of organized this lecture was how the numerical method is used in the design and analysis of techniques to give approximate but accurate solutions to hard problems, In addition, the purpose of most numerical analysis research is to develop actual computer codes to solve real problems; and thus the development of computer software to implement numerical algorithms is an important part of the subject. This lecture was organized for BCA-III year students. 32 interested students participated into this lecture. They learned the basic concept and use of the applications of Numerical Methods. Prof (Dr.) Mukesh Kumar Sharma, Department of Mathematics, CCS University Meerut told that Numerical Methods forms the foundation of many of the machine learning algorithms. Therefore, he introduced some of the basic machine learning problems as a motivation for students to learn more tools and skills to solve problems in the future. The motive behind this lecture was to give the expose the students to the topic “Numerical Methods in Computer Applications”. The session aimed at providing the knowledge of various mathematical operations and tasks, such as interpolation, differentiation, integration, the solution of linear and nonlinear equations, and the solution of differential equations.
