INTRODUCTION
1.1 Background
This project is based on design an e-learning tool about Harmonic analysis to help student in their study. E-learning is a type of education in interactive way by using the computer as a
medium of learning. E-learning is used interchangeably in a wide variety of contexts. This project also helping the lecturer to assist their student understands the topic.
