DAY 1: 25 May

Type a 100-word reflection for today's lesson.
I feel that this two topics -- Mid-point and distance between two points, are quite easy to understand. I feel that the formula on midpoint is quite common sense as long as you understand coordinate geometry. The topic on distance between two points is quite interesting as it makes use of the pythagoras theorem to find the distance between two points. Although the formula is easy, it can be very hard if you do not know how to apply it, like question 4 and 5. In conclusion, the video resources are very clear in explaining the concepts and i learnt a lot from this lesson.

DAY 2: 26 May

Type a 100-word reflection for today's lesson and comment on your work.
I feel that this topic is much harder then yesterday's topics. I don't quite understand the last slide of the powerpoint, where you are asked to find the radius and center of the circles from another form of the equation. However, i managed to grasp the concept of r being the radius, a and b being the coordinates of the center of the circle, and what changing them would result in. Thus making the design with the graphic calculator is not as hard as i imagined. However i forgot how to use the graphic calculator so i did not manage to remove the axis.
