A differential geometry question.

Click For Summary
SUMMARY

The discussion centers on finding a smooth plane curve \( r \) of length \( L > 2 \) that connects the points \((-1, 0)\) and \((1, 0)\) while maximizing the area of the bounded domain \( D \) in the upper half-plane. The problem is framed as a calculus of variations challenge, where the optimal curve must be determined to achieve the maximum area. The conversation highlights the mathematical nature of the problem, emphasizing that it is not merely a request for answers but an exploration of differential geometry concepts.

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.
