A Tale of Two Integrals

Year of Award: 2000

Publication Information: The American Mathematical Monthly, vol. 106, 1999, pp. 227-240

Summary: This paper presents several approaches to a simple-looking combinatorial-analysis problem with the aim of showing how different ideas can lead to a solution.  The analysis version of the problem can be stated as follows: If \(f\) and \(g\) are functions each having integral over \([0,1]\) equal to \(1\), then there is some subinterval of \([0,1]\) over which each integral is equal to \(1/2\).
