For those who care, you can save the Koch Chart as a picture
file to your computer. Then open it with PAINT or some
other photo editing program. Locate the x,y coordinates for
each part of the graphs and then use those numbers to solve
the algebra problem to get the formula for the system of
equations. Or just use the chart and add a cushion for
safety.
