^= squared
Head
1.5x^2+y^2=r^2 used to make circle. circles taught by Ms McArthur
r=10 used to change size
nose
40x^2+40y^2<=r^2 made circle and used < to make it filled in. shading taught by Ms McArthur
eyes
\left(x+-3\right)^2+\left(y-4\right)^2<=1 made circle eyes, < to fill in
\left(x+3\right)^2+\left(y-4\right)^2<=1
mouth
.2x^2+-6.5\left\{-2.5<x<2.5\right\} made smile, <x< to limit how far it goes. found out through experimentation
pupils
\left(x+-3\right)^2+\left(y-4\right)^2=.01 made pupils in middle of eyes. shrink the size of circles to make pupils
\left(x+3\right)^2+\left(y-4\right)^2=.01
freckles left
\left(x+-4\right)^2+\left(y-1\right)^2=.01 made small dots to represent freckles
\left(x+-5\right)^2+\left(y-0\right)^2=.01
\left(x+-3\right)^2+\left(y-0\right)^2=.01
\left(x+-4\right)^2+\left(y+1\right)^2=.01
freckles right
\left(x+4\right)^2+\left(y+1\right)^2=.01
\left(x+3\right)^2+\left(y+0\right)^2=.01
\left(x+5\right)^2+\left(y+0\right)^2=.01
\left(x+4\right)^2+\left(y-1\right)^2=.01
eye brows
y=\cos\left(x+3\right)+5\left\{1<x<5\right\} made wavy line and used <x< to limit how far it goes. learned by experimentation
y=\cos\left(x+3\right)+5\left\{-4.6<x<-1\right\}
hair
y=\cos\left(x+5\right)+9\left\{-3.9<x<5.5\right\} made wavy lines, <x< to limit length. learned by experimentation
y=\cos\left(x+3\right)+9\left\{-4.6<x<5.5\right\}
y=\cos\left(x+1\right)+9\left\{-4.1<x<5.5\right\}
