KAS 103T ENGINEERING MATHMATICS I 

3L:1T:0P 4 Credits 

COURSE OBJECTIVE: The objective of this course is to familiarize the graduate engineers with techniques in calculus, multivariate analysis, vector calculus and linear algebra. It aims to equip the students with standard concepts and tools from intermediate to advanced level that will enable them to tackle more advanced level of mathematics and applications that they would find useful in their disciplines. The students will learn:
To apply the knowledge of differential calculus in the field of engineering.
To deal with functions of several variables that is essential in optimizing the results of real life problems.
Multiple integral tools to deal with engineering problems involving centre of gravity, volume etc.
To deal with vector calculus that is required in different branches of Engineering to graduate engineers.
The essential tools of matrices and linear algebra, Eigen values and diagonalization in a Comprehensive manner are required.
