On the ellipsoid and plane intersection equation

open access: yes上海师范大学学报. 自然科学版, 2018
Let E:(x2)/a2+(y2)/b2+(z2)/c2=1 be an ellipsoid and P:px+qy+rz=d be a plane.Based on the Householder transformation,it is shown that the intersection E∩P is nonempty if and only if λ ≥ |d|,where λ=√(ap)2+(bq)2+(cr)2.When λ>|d|,this paper provides a
