In view of the Movement Control Order imposed starting on 18th March 2020 due to the severity of the Covid-19 virus, all the teaching and learning process is now done via online. The materials below have been shared in YouTube and will be updated from time-to-time.

One of the first online lecture which I have developed was on the topic of line integral and vector field. In these videos below, I showed how to plot vector field using Octave and to understand if a certain path to reach a certain point in space requires less or more energy.

- Plot vector field using Octave – Part 1
- Vector field from a scalar potential – Part 2
- Example of non-conservative field – Part 3

More videos can be found in the links below, sorted according to topics covered during the semester.
