The topic on finding midpoint and distance of the line is indeed very interesting and enriching for me today. This topic is in general, rather easy to understand, and I feel the only thing left is the speed of completing the questions. I tend to be a little slower today because the x intercepts and y intercepts was rather confusing at certain points of time. Nonetheless, this topic was fun. I had never thought we could use Pythagoras Theorem together with coordinate geometry. This goes to show how topics of math are always interlinked and can be used hand-in-hand together.

DAY 2: 26 May

Type a 100-word reflection for today's lesson and comment on your work.

Day 2 Reflections:
The use of graphic calculator was rather difficult - firstly, because my macbook faces some technical difficulties with the graphic calculator, and secondly, because the conversion of equation to make y the subject was rather confusing. In the end, after traveling to my classmate's house and spending 1 hour gruesome hour there doing the London Olympics graph, I finally managed to complete it. However, I don't think I might be able to complete design 2, 3 and 4.Nonetheless, I will still try my best. The grraphic calculator is indeed very intriguing.
