Question

find the unit normal to the surface x^3 -xyz+z^3=1 at (1,1,1)​

Answer 1

Answer:

Keywords: minimal surface, Gaussian curvature, quaternions, octonions ... that the intersection of K with the standard unit sphere S3 is the torus T = S1 × S1 ... 2) cos α, x1. = (1/. √. 2) sin α, x2. = (1/. √. 2) cos β, x3. = (1/. √. 2) sin β. (1.1) ... In order to find the second quadratic form, we should project the second derivatives of.
