Background reading/watching for Jacobian / change of variables

here are some videos and web pages that might make good background reading / reference links for our teaching materials:

2 nice videos from Khan Academy:


Khan Academy - Published on Jan 10, 2017
“Before jumping into the Jacobian, it’s important to make sure we all know how to think about matrices geometrically. This is targetted towards those who have seen linear algebra but may need a quick refresher.”

Khan Academy - Published on Jan 10, 2017
“How to interpret the determinant of a Jacobian matrix, along with some examples.”

basic/short video - narrator computes the jacobian on the whiteboard, step by step:
