Mathematicians use the term chaotic to describe systematic, nonrandom processes that produce results that look random. Chaos theory helps scientists understand the turbulent flow of water, the mixing of chemicals, and the spread of an oil spill. Your calculator can repeat steps quickly, so you can use the calculator to plot thousands of points. Step 10 Enter the Chaos program into your calculator. [ See Calculator Note 0E for the program.
