Complex number

Back when I was still studying in University, there wasn’t much time for me to just sit back and appreciate what I have learnt. There are so many questions that in me that remain unanswered. Out of the many questions, one stands out over the others. “How is Engineering Math relevant to the real world?”.

I have been spending some time lately, flipping through my lecture notes, trying to learn all over again with a new understanding. What I have gained from this is truly amazing.

Since many of us have to stay home for at least a month now, I encourage you to do the same too.


Before this blog becomes irrelevant, I would like to share some amazing YouTube videos that I came across a few days back. You may find these video very basic, but to understand the complexity of semiconductors, I feel that having a strong foundation is necessary.

Update 5

Apologies on the downtime. As I have not been monitoring this website due to the heavy workload from my workplace, the domain expired without me noticing.

Anyway, keeping this website up costs USD$18.00 annually. If this website has helped you and you would like to show your appreciation, you can either:

  1. Donate money through the donation button somewhere at the side.
  2. Donate your tutorial materials. (Send me a message through feedback)

Once again, sorry for the downtime. Let your friends know that the website is online again and spread words on this website to the freshmen who are coming in this year.

I graduated last year anyway.

Update 1

Hi friends,

This semester has been my hardest (but also the most fulfilling one) which explains why there is some delays in uploading the tutorials.

I’ve uploaded the first 5 tutorials for Engineering Math I.

I probably will not upload Data structures & Algorithms tutorials. Answers are scribbled all over the tutorial question papers. If you still insist on having it, drop me a feedback.

All the best for mid term.


More is less. Less is more.
