DAY 1: 25 May



I felt that today home learning was quite easy to understand as the formula was quite clear and straight forward. The formula taught also uses the principals of Pythagoras Theorem which we had learn before, allowing me to get a greater understanding. However, finding the distance and the mid-point prove to be a confusing task as I tend to mix up between the two formulas eg adding when finding the distance, subtracting when finding the midpoint. In conclusion, I feel that this lesson had been a very enriching and fun exercise but I feel that I still need more practice.

DAY 2: 26 May


I felt that today home learning was a little harder to grasp the concept as compared to finding the distance and the mid-point. The concept also uses the principals of Pythagoras Theorem to find the radius of the circle, allowing me to have a better understanding. However, the formula of finding the equation of the circle is troublesome, causing me to be confused with the formula, making many careless mistakes. Eg. I might mix up between the two points (x,y) and (a,b). All in all, I feel that this lesson had been very challenging and enriching but more practice is needed in order to work out the equations quickly.
