Find equation. to the cone with vertex at (0, 0, 0) which passes through the curve of intersection of plane lx + my + nz = p and ax2 + by2 + cz2 = 1.
1
p2/4(ax2 + by2 + cz2) = (lx + my + nz)2
2
p2(ax2 + by2 + cz2) = (lx + my + nz)2
3
(ax2 + by2 + cz2) = (lx + my + nz)2
4
p2(ax2 + by2 + cz2) = (lx - my - nz)2
