Very impressive, Ron.

Tell me, is finding composite function components required in calculus? - Jan 20th 2007, 01:42 PMCaptainBlack
I don't know I have never followed the US maths course sequence (we

don't/didn't do things that way in the UK). As far as I recall we learned

stuff as it was needed.

Some knowledge of composite functions is needed for the chain rule, but

as far as I recall a formal treatment of composite functions was not needed

in the courses I pursued until the transition to university real analysis (1st

year undergrad maths here).

Maybe one of our US helpers will be able to answer your question better.

So, you are from the UK? Interesting.

Thanks!
