The Roman surface or Steiner surface is a selfintersecting mapping of the real projective plane into threedimensional space, with an unusually high degree of symmetryThis mapping is not an immersion of the projective plane;X2y=8 graphically and find the coordinates of the points where corresponding lines intersect y Explanation Making m = x −y n = y −z p = x −z we have m2 n2 p2 = 2(x2 y2 z2 − x ⋅ y − x ⋅ z −y ⋅ z) then x2 y2 z2 −x ⋅ y − x ⋅ z − y ⋅ z = 1 2((x − y)2 (y − z)2 (x −z)2) Prove That X2 Y2 Z2 Xy Yz Zx Is Always Positive Brainly In X^2 y^2 z^2-xy-yz-zx is always positive
