Specific Objectives of course:

Linear algebra is the study of vector spaces and linear transformations. The main objective of this course is to help students learn in  rigorous manner, the tools and methods essential for studying the solution spaces of problems in mathematics, engineering, the natural sciences, and social sciences and develop mathematical skills needed to apply these to the problems arising within their field of study; and to various real world problems.
