Fix a number L > 2. Consider all smooth plane curves r of length L that connect (−1, 0) and (1, 0) and are contained in the upper half-plane. Note that and the segment [−1, 1] of the X-axis together bound a plane domain D. Find r such that D has the maximal possible area.(adsbygoogle = window.adsbygoogle || []).push({});
