The Quotient Rule

In this video, I will go over multiple examples of the quotient rule. Also, I will show that you don't always need to use the quotient rule.
Remember this saying to help memorize the quotient rule...
"Low D high minus High D low divided by Low Squared"

is this kind of song remembering style really useful to anyone? why not just remember it is an antisymmetric expression on the top, the bottom gets squared and then you just fit for the case g=1 to figure out what gets subtracted from what?

I taught it both ways over the years and students definitely remembered it easier with the saying. Thanks for watching !
