Hello, colleagues I was tasked to find the intersection between a surface and a plane which are (x-y)^2 + (y-z)^2 + (z-x)^2 = 2^(1/2) x + y + z = 1 The intersection should be found under a condition which is x >= y >= z.
However, the result using ContourPlot shows some gray things as well as the intersection. Could you tell me how to delete the gray things or other functions rather than ContourPlot?
Thanks in advance.
