DAY 1: 25 May



DAY 2: 26 May

I felt that today's work was very challenging. I am new to the concept of using graphs and equations to generate circles on the graphic calculator. I find it very tough. Drawing these circles are also very tedious as I have to change the equations once I find that they are wrong. Up till now, I am still struggling to draw these images. Only with the help of my classmates, then I was able to do some.
