DAY 1: 25 May

Type a 100-word reflection for today's lesson.

From this online lesson, I found that Coordinate Geometry is more complicated than I expected. With the graph to me already rather difficult, this was a higher level. We were assigned to find the distance between coordinate points with the formula of square root of x2-x1 + y2-y 1. With the distance and mid-point formula, it was much more easier to answer the questions. However, the questions were not easy and challenging to me, which I understood that I did not understand the chapter well. With this lesson, this topic would be easier for me to answer questions of this chapter and is beneficial.

DAY 2: 26 May

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

The online lesson was rather complicated in a way and easier in another sense. The easier part was the memorization of the formula to find the equation for the circle in the standard way. Distance equals to the square root of (x2-x1)to the power of 2 + ( y2-y1) to the power of 2. This formula was easier but the complicated part totally overpowered this formula. The graphic calculator design drawing was rather difficult and thus, I was only capable of finishing 1. The other 2 design were completely messed up or either halts half-way. Therefore, I feel that today’s lesson was rather complex but interesting.
