DAY 1: 25 May

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


I feel that the lesson today was quite simple. I have not heard of midpoints of lines and distance between two points on the graph and this lesson really allowed me to broaden my horizons and take a step deeper into the world of coordinate geometry. Through the different videos posted on the website, I was able to understand the two new topics quickly as the videos were very enriching and resourceful. I feel that I am still slight slow in doing these problems and I will try to do more practices to keep myself well trained in this topic so that it will seem easier during the tests.

DAY 2: 26 May

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

I felt slightly lost when I was navigating around the graphic calculator as we did not have practices on quadratic for some time. The new addition of drawing circles is definitely a big boost as now I am better equipped with more different shapes to complete a GC design. I think that the equations of circles were fairly easy to understand and the youtube videos and the applet made this topic much easier to comprehend. The Olympic Rings design was fairly easy to complete but I am not sure if there is a way to make the rings interlock with each other as shown in the picture provided on the website. The other two designs are very difficult but I will continue trying and hopefully, I will be able to create the designated image.

Design 2:
y1= 3 + sqrt(9-(x-3)^2)
y2= 3 - sqrt(9-(x-3)^2)
y3= 7 - x/(2 <= X)/(x<=4.5)
y4= 2/3 *(2x-0.5)/(2<=X)/(x<=3.1)

Design 3:
syringe only:
y1= 2/(1<=x)/(x<=5)
y2= 1.5/(1<=x)/(x<=5)
y3= -1.5x + 3.5/(0.5<=X)/(x<=1)
y4= 1.5x/(0.5<=X)/(x<=1)
y5= -.25x + 3.25/(5<=X)/(x<=5.75)
y6= .25x + .25/(5<=X)/(x<=5.75)

curves:
y1= 1.75+(1.56-(x-3.75)^2)^1/2 /(2.19<=X)/(X<=3.75)
y2= 1.75-(1.56-(x-3.75)^2)^1/2 /(2.19<=X)/(X<=3.75)
y3= 1.75+(1.1-(x-3.75)^2)^1/2 /(2.65<=X)/(X<=3.75)
y4= 1.75-(1.56-(x-3.75)^2)^1/2 /(2.65<=X)/(X<=3.75)
y5= 1.75+(1.56-(x-2.5)^2)^1/2 /(0.94<=X)/(X<=2.5)
y6= 1.75-(1.56-(x-2.5)^2)^1/2 /(0.9<=X)/(X<=2.5)
y7= 1.75+(1.1-(x-2.5)^2)^1/2 /(1.4<=X)/(X<=2.5)
y8= 1.75-(1.1-(x-2.5)^2)^1/2 /(1.35<=X)/(X<=2.5)
y4= 1.75+(1.56-(x-3.75)^2)^1/2 /(2.65<=X)/(X<=3.75)
