I know this sounds like a strange, maybe impossibly naive question, but I have a B.S. in Math and have done some graduate work and I find myself teaching the chain rule and product rule to undergrads. I can get some intuition on why the rules work the way they do, but I find I can't think of any good simple concrete examples of why we would have functions for things and then multiply or compose those functions. What are some nice examples of this?(adsbygoogle = window.adsbygoogle || []).push({});
