So I was looking at the quotient rule for the second derivative and momentarily wondered what the third derivative might look like. Vince commented that it would be really cool if it followed Pascal's triangle. Something like this maybe: $$u'''(x)=\frac{u(x-h)-3 u(x)-3 u'(x)+u(h+x)}{h^2}$$Just a random idea. I'll play around with it after the quiz, see if I can use the same Taylor expansion trick.
