On to the Challenge!
Can you create the following graph using desmos.com or some other graphing tool? If you’re victorious, leave us a note in the comments when you’re done.
Terrence made this great Desmos Sketch!
This is what I got:
x^2+y^2=1
x^2+y^2=4
x^2+y^2=9
x^2+y^2=16
x^2+y^2=25
x^2+y^2=36
x^2+y^2=49
x^2+y^2=64
x^2+y^2=81
I couldn’t figure out how to shade the circles, however. I spent a long time pressing every button I could to try to figure it out and came back unsuccessful.
Great! All you have to do to shade is to change the = sign to a <= sign!
x^2+y^2<1
x^2+y^2<4
x^2+y^2<9
x^2+y^2<16
x^2+y^2<25
x^2+y^2<36
x^2+y^2<49
x^2+y^2<64
x^2+y^2<81

x^2+y^2<1
x^2+y^2<4
x^2+y^2<9
x^2+y^2<16
x^2+y^2<25
x^2+y^2<36
x^2+y^2<49
x^2+y^2<64
x^2+y^2<81
x^2+y^2<1
x^2+y^2<4
x^2+y^2<9
x^2+y^2<16
x^2+y^2<25
x^2+y^2<36
x^2+y^2<49
x^2+y^2<64
x^2+y^2<81
This is what I came up with:
x^2+y^2<=1
x^2+y^2<=4
x^2+y^2<=9
x^2+y^2<=16
x^2+y^2<=25
x^2+y^2<=36
x^2+y^2<=49
x^2+y^2<=64
x^2+y^2<=81
