Re: Composition of Functions

Hi MathsisFun;

Looks nice and explains it well. Didn't find anything wrong with it. What is your opinion of how they do it here and do you think it is worth adding something like this:

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.
