Note that the definition is symmetric with respect to the two curves—the Fréchet distance would be the same if the dog were walking its owner. Formal definition [ edit] Let be a metric space.
Web23 okt. 2024 · No, it's not necessary that the x exists in both lists. Say, there could be an x-value around 108 where the vertical distance between the 2 curves is the max, and does not exist in either list. The difficult part for me is how to find such x value. Do you get some idea? – Miao Oct 23, 2024 at 15:35 1 Web1 Answer Sorted by: 1 Create your distance function f ( x) = 2 + sin x − cos x and take its derivative f ′ ( x) = cos x + sin x. The minima and maxima occur where f ′ ( x) = 0, i.e., sin x = − cos x. There are trigonometry techniques for finding those points.
