hello
you can do the custom tool yourself

if you need I can do it
Hi lawrence!
One possibility is to use Binet's Formula: https://en.wikipedia.org/wi...
You can use it e. g. in CAS in numerical modus, so you get the FibonacciNumbers in a directly and not in a recursive form.
That makes it quite easier to define the squares and arcs in a sequence command.
I think, you can manage it now.
Kind Regards

if you want to use the Binet formula the tool is easier because you need less poinst in sucesive steps because An+1/An is known
