Operations with FunctionsPlease have a look at Operations with Functions and tell me anything wrong or lacking, thanks. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #2 20091008 22:48:40
Re: Operations with FunctionsLooks mostly good, but in your 'But Not Always' section you've got an (x1)² where there should be an (x3)², and there's an 'ex' that looks like a typo. Why did the vector cross the road? It wanted to be normal. #3 20091009 08:49:26
Re: Operations with FunctionsThank you. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #4 20091009 09:23:45
Re: Operations with FunctionsHow about f(x) = x + 1/x and g(x) = x "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #5 20091009 10:16:10
Re: Operations with FunctionsHi MathsisFun; Last edited by bobbym (20091009 10:17:40) 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.
