Boxing Clever

"Boxing Clever", by Martin Hansen, shows how tired old clichés lead to
new insights when theory is confronted with grim reality.
The cliché is calculus, but the textbooks & Sainsbury's disagree on the answer.
Sainsbury's is right.
You will never see a humble cardboard box in quite the same light again.
This is a thoughtful Sixth Form level item on Calculus.
