COURSE OBJECTIVES:

• To acquaint the students with the concepts of vector calculus which naturally arises in many engineering problems.
• To introduce Fourier series analysis which is central to many applications in engineering apart from its use in solving boundary value problems.
• To acquaint the student with Fourier transform techniques used in wide variety of situations.
• To make the students appreciate the purpose of using transforms to create a new domain in which it is easier to handle the problem that is being investigated.
• To introduce the effective mathematical tools for the solutions of partial differential equations that model several physical processes and to develop Z transform techniques for discrete time systems.
