Format To Iterate For CHAOS Calculation

I have never used EXCEL before, but I have a copy of EXCEL 2000.

My question should be easy to answer for experienced EXCEL users
(I hope ).

QUESTION:
1. Where can I find a DETAILED example that shows how to use EXCEL to
calculate the iterated CHAOS function A*x(1-x) ??

for:
1.1 A = 2.0; x0 =0.01 // simple converging function

1.2 A = 3.3; x0 =0.02 // period-2 orbit

2. THe example would be great if it included a DETAILED example how to produce using EXCEL.
