5900f4641000cf542c50ff76 | Problem 247: Squares under a hyperbola | 5 | 301894 | problem-247-squares-under-a-hyperbola |
--description--
Consider the region constrained by 1 ≤ x
and 0 ≤ y ≤ \frac{1}{x}
.
Let S_1
be the largest square that can fit under the curve.
Let S_2
be the largest square that fits in the remaining area, and so on.
Let the index of S_n
be the pair (left, below) indicating the number of squares to the left of S_n
and the number of squares below S_n
.
The diagram shows some such squares labelled by number.
S_2
has one square to its left and none below, so the index of S_2
is (1, 0).
It can be seen that the index of S_{32}
is (1,1) as is the index of S_{50}
.
50 is the largest n
for which the index of S_n
is (1, 1).
What is the largest n
for which the index of S_n
is (3, 3)?
