Consider the paraboloid z=x2+y2. the plane 4x−8y+z−10=0 cuts the paraboloid, its intersection being a curve. find "the natural"
VladimirAG [237]

4x-8y+z-10=0\implies4x-8y+x^2+y^2-10=0


Complete the square to get


x^2+4x+4-4+y^2-8y+16-16-10=0


(x+2)^2+(y-4)^2=30


Now let


x+2=\sqrt{30}\cos t

y-4=\sqrt{30}\sin t


and the intersection can be expressed as a function of t,


\mathbf r(t)=(\sqrt{30}\cos t-2,\sqrt{30}\sin t+4)


with 0\le t\le2\pi.
