Larry,
Very nice use of the web browser and plugin to show the step-by-step
derivations! For the first one, I enjoyed the animation of dividing both
sides by "n" in the last step. :-)
Also, Example 1 at the bottom of the page was nicely done, with respect to
the repeated use of the substitutions.
Good work!!! (Wish I had such clear deliveries when I was taking this stuff!)
