Hi;

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 have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

hi MathsIsFun

Those pages are excellent; you have made it crystal clear.  If only I'd had that clarity 46 years ago ... smile

Many thanks.

Bob
