Needing a break from studying, you take a walk to the Pogonip koi pond, whereupon
a wild-eyed stranger pops out from behind a redwood tree and directs the following polemic
in your general direction: "The lies those so-called teachers at that university promulgate, let
me tell you. I know the truth that they don't want you to know. As plain as day, " = 0
for all n ≥0. It's an easy induction proof, see?" He hands you a leaflet, where you see the
proof that they don't want you to see:
We proceed by strong induction on n.
Base case: n = 0. We have 10:
Induction step: Assume that
d1 =

= 0.
dx

dx
= 0 for all kn. Then, by the product rule,
nd
dx
da
1x+1 = 1/1(x²x²) = x²±²x² + x 11 x²
d
=
x.0+x¹.0 0.
dx
This completes the induction.
That derivative rule doesn't seem like the one you learned, but there's nothing obviously
wrong with the proof. Is he right, are the math professors propping up the interests of Big
Calculus? Or should he have paid better attention in CSE 16? What's going…
