Objectives and Outcomes
Course Objectives:The objective of this course is to introduce the Fourier and Laplace transforms, and the uses of these transforms in the solution of partial differential equations. This course is intended to lay a mathematical foundation to other theoretical courses such as quantum mechanics and act as a primer to a student who opts to take up a higher course in physics.Course Outcomes:At the end of the course, the students will be able to:CO1: Understand and Apply Fourier Analysis to various types of periodic functions CO2: Understand and Analyze Fourier Integrals and TransformsCO3: Understand the significance of Laplace Transforms and apply it to various problems CO4: Understand the methods of solving PDEs using Series and Transforms.
