The output

The output for this scenario is shown in Figure 6 .

Figure 6 . Output for rotation of the axes for simplification.

Once more, I will allow the comments in Listing 4 to serve as the explanation for the solution of this scenario.

Run the scripts

I encourage you to run the scripts that I have presented in this lesson to confirm that you get the same results. Copy the code for each script into atext file with an extension of html. Then open that file in your browser. Experiment with the code, making changes, and observing the results of your changes. Makecertain that you can explain why your changes behave as they do.

Resources

I will publish a module containing consolidated links to resources on my Connexions web page and will update and add to the list as additional modulesin this collection are published.
