Linear approximations aren’t very intuitive when you’re only looking at symbols on a page. In this problem, I make it easier to understand how and why linear approximations are useful, and make it easier to digest by using a physical example — a cylinder.

This video helped a lot with linear approximation for a cylinder on the homework assignment. It explains it the hard way, but in a way that helps because you understand more in depth what you are trying to approximate, and what the values actually mean. This video was very helpful.
It's cool to see linear approximation applied to a cylinder. We don't typically see it this way. By striving to understand more complex applications of linear approx, the simple stuff and big concepts become clear much easier.
