Question: (a) Find the highest and lowest points on the ellipse of intersection of the cylinder \(x^{2}+y^{2}=1\) and the plane \(x+y+z=1\)
(b) Find all minimum and maximum points of the function
\[u(x, y, z)=x y z\]on the circle in \(\mathbb{R}^{3}\) formed as intersection of the plane
\[x+y+z=1\]and the sphere of radius 1
\[x^{2}+y^{2}+z^{2}=1\]
