DAY 1: 25 May


I feel that this lesson is quite easy to understand, yet troublesome. The troublesome part is that we have to view the entire video to understand the theory.Personally, I prefer to have text-based notes as, it will take some time to load the video and sometimes there are glitches. This lesson is quite easy to understand as theories from previous lessons, like the Pythagoras Theorem, are utilised to help us understand this quickly. Regarding the problems I had with the wikispaces, I am quite sure that it is not only me. I think we should just stick to the old wikispaces, and submission through IVLE, as it is very easy for people to view one another's answers, thus may lead to slight copying.

DAY 2: 26 May

I find the lesson today very interesting as we get to challenge ourselves to create the designs with the Graphic Calculator. I was quite confused with the a and b variables with x1, x2, y1, y2. But after looking deeper into the topic, I understood the concept soon.
