Thanks for the pages. I always have trouble with these. Looks good to me but better get some other opinions too.
In mathematics, you don't understand things. You just get used to them.
I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.
Those pages are excellent; you have made it crystal clear. If only I'd had that clarity 46 years ago ...
